Well, looks like /. ate and posted an incomplete post of mine. I guess I won't try writing any posts from my phone in the future, if their UI is going to be this crappy. Let's try again, with a few revisions:
I think she's calling for a bit too much out of Apple.
Apple is a hardware company; any products or services they offer other than hardware are only relevant to them because they think it'll help them sell hardware. Apple also has a justified complex regarding self-sufficiency. More on that presently.
When listening to compressed music on computers began to take off, Apple responded by buying SoundJam MP, modifying it, and releasing it as iTunes. Mostly this was to sell computers -- making sure that people knew that Macs were well-suited to storing, organizing, and playing music files, and could also rip and burn CDs. It was also part of their complex to not rely on third parties to provide important features, and this was now deemed an important feature, with the iPod beginning development shortly after the purchase of SoundJam, and with iTunes to be the syncing software for it.
Releasing a Windows version of iTunes, and selling music via the iTunes Music Store were both just strategies to sell more iPods. Apple figured that some people would buy downloaded music at the 99 cent price point, and that some of them might even be former pirates. The store's label-mandated use of DRM would also help lock customers into the iTunes ecosystem, helping to sell more iPods.
Streaming is just more of the same; because of free streaming, many people who would buy music, or who would pirate music, have flocked to listen to music legally for free (at the expense of having to use bandwidth to stream, not having offline copies, and losing some degree of choice in what you're listening to when. Also, ads). While the iPhone is now more important than the iPod, Apple likes having people locked into the iOS ecosystem. They like having people buy iOS devices, on which music listening is still a core feature (and will continue to be, e.g. with the CarPlay platform). Streaming has become important, and like all important things, it can't be left in the hands of third parties. Therefore Apple must provide music streaming.
But music streaming is a crappy business. Almost all the users stay in free tiers; a mere handful actually pay. Apple's plan is to draw users in with a free time period and then hope for a good attach rate when the time comes for users to either cancel or pay to subscribe. I doubt that Apple will get more than 10 million paying customers (and therefore will only get revenues of around $200 million their first year, and around $300 million in later years after accounting for payments to rightsholders). Frankly, they can find more money than that in their couch cushions. Apple isn't interested in streaming for how profitable it is (read: it really isn't). And I'm sure that they know that in the absence of free streaming, most people will go right on back to pirating music again (with some returning to the iTunes Store, which suits Apple fine).
The whole point of Apple's streaming service therefore is just to keep their hand in, and to prevent a potential rival from being in a position where Apple is so dependent on the rival that the rival has power over Apple.
So can Apple pay rightsholders during the free period? I'm sure they can afford it. Although it makes no economic sense for Apple, as it would cost over $20 million per million free users, and with low attach rates expected, this could easily run over a billion dollars in payouts for a business expected to generate far far less than that. It's frankly not important enough to them to do it. Putting up with Taylor Swift whining at them, and rightsholders loudly complaining that the world is no longer stuck in the 80's and early 90's, is not too big of a cross to bear.
Apple's options other than a free trial period are a free tier, or no free anything. We already know what Swift thinks about the former. The latter is the plan that Tidal is pursuing, plus a higher subscription rate. I don't think it's going to fly. Whether or not it is a legal substitute, piracy is a real substitute, and can't be ignored. If music costs too much to get, people will gladly pirate. Hell, they'll often pirate just for the joy of it. And for a lot of people, any amount of money out of their pockets is too much. Tidal will not be able to reverse the tide of piracy, and asking Apple to follow in its footsteps will neither change the reality of the music industry nor convince Apple to actually do it, given the relative unimportance of legal music for them at this point.
So by all means, she has a right to complain. But I don't see the numbers working out in a way that will put any force behind her complaints. The music industry will have to collapse further, and be rebuilt anew, before it can become viable again, if it ever can.
Regarding Apple's complex about self-sufficiency, it's due to a history of sudden but inevitable betrayal. In 1978, Apple licensed Microsoft BASIC (renamed Applesoft BASIC) because Apple never got around to finishing floating point routines for their own BASIC. The license was for 7 years. The renewal came up in 1985, at a time when Apple still relied on the profits of the Apple II line, all of which had Applesoft BASIC in ROM. Apple hadn't ever gotten around to making a perfectly compatible new BASIC, which meant that MS had them by the short hairs. Luckily, all MS wanted to renew the license was for Apple's BASIC for the Macintosh to get canceled, which it was.
Later, MS again had great power over Apple, because Apple needed MS Office to be available for the Mac, and MS has both used this as a sword and also never quite made it as good as the Windows version. Now Apple has made their own little office suite just to have some alternative available. (It's not quite a substitute, but it's something, especially for casual users)
Then as Netscape collapsed, Apple needed a good web browser, and had to make a deal with MS for IE. The ultimate response for that was for Apple to write their own browser, Safari.
The original (Google-based) Maps program for the iPhone started as just a demo for scrolling, IIRC. It rapidly became an invaluable feature, but Google became a competitor, and withheld new features seen on Android's version of Maps from the iPhone. Therefore Apple had to develop its own Maps program. (And should've seen this coming as early as 2008)
Why did Apple get into the ebooks business? Because Amazon dominates it, and Apple saw that the iPad might make a good ebook reader. Therefore Apple had to have its own alternative option, not to seriously compete, but to make sure that Amazon couldn't kill off the iOS Kindle app, thus harming iPad sales to people who wanted to read ebooks on iPads.
Ginning up a rival to Spotify & co. is just more of the same.
