For it to be ethical it would have to be a very clear opt-in procedure, not something buried in a ToS somewhere.
It's not good business to irritate your customers, unless it doesn't matter because you have them locked into your service due to a virtual monopoly.
Looking to find and fill a genuine need for your customer = good.
Trying to sell them something they obviously aren't there for (such as additional services when they are looking for tech support) = bad.
Continuing to bother a customer when they tell you that they're not interested = terrible.
Unfortunately, the summary doesn't really make that clear.
It's still a terrible idea. For the most part, the other car companies won't innovate unless they have competition. Tesla is far more likely to create real change by existing as a car company than they are by existing as a parts company.
"As far as I can tell, ObamaCare has not a single defender outside the ranks of Obama's defenders and the Democratic Party."
Let me guess, how can you tell if someone is an "Obama defender?": they defend "ObamaCare!"
This isn't something new. Before I got into the tech industry I worked in insurance for a major US retailer back in the 90s. While there, 60 Minutes did an "expose" on the dangers of shopping carts. Lots of discussion of people and children hurt around shopping carts, but not one word about now 99%+ of those accidents are a result of people stupidly using carts in ways they weren't intended to be used. Pointing that out would have gone against the narrative they were trying to construct about how inherently dangerous shopping carts were.
The truly amazing thing to me is that so many people can see journalists routinely get things wrong about subjects those people are personally knowledgeable on, yet still trust those same journalists on any other topic they cover.
This was similar to my experience. I bought about an album a month before Napster, while Napster was around I bought at least an album a week, and after it went away I dropped back to about two albums a year. I'm now back to buying the equivalent of about an album every other month through iTunes.
So, a decade later and I'm still spending a lot less money with them than I was when Napster was around. Multiply that by everyone else who acted in similar ways, and it's not so hard to determine the real reason for their declining income.
