Lets take game series as examples - even if your studio created the game and the franchise, the IP rights to the name, characters etc belong to the publisher as they financed it and that was the deal made with the studio. Unless they make a deal with the publisher, they also cannot just leave and continue using that same name under another publisher. On the other hand, the publisher has the right to use the name even if they hire a new studio the make it. This is the case with Call of Duty series too. It's basically work for hire, and it's a decision creators make when thinking if they could finance it on their own or if they need a publisher to finance the initial creating part. Since publisher takes a risk, they also get to own the work done.
It's the same thing when you work for a software company as coder. You don't own the product or the code you made, as you were hired to do it for the company. If you want to keep it all to yourself (and also get larger rewards), you need to finance and handle all parts of it yourself.
Re Nokia, I'm not seeing that much change in their stock price. Yes, they're up and a bit today, but that only covers the previous months decline... but maybe I'm missing something.
They're up 15% immediately after the announcement. That tells something.
Bing toolbar used to follow what links people clicked on search results. That way Bing also got the information about such nonsensical keywords. But if no user clicks those links, they don't get those results. Bing doesn't just scrape Google, they collect usage information (like Google does too).
It's always nice to see somehow spewing complete bullshit when he either doesn't understand the issue or knows no one will actually try it, and try to come off as wiser than he actually is.
