Someone using the pics for unpleasant deeds sounds like a very unlikely case. I mean, I am sure there are lots of pictures of famous people on the public domain, yet I can't remember any case where they were used like that to make a legal business. The point is, the danger of someone using pictures of the famous for unpleasant, legal, deeds, already exists, and I don't see how it could be exacerbated by having higher quality pictures freely available on Wikipedia.

Someone else pointed out above that they would be willing to take a photo for Wikipedia, but they would just charge more for it, as they cannot restrict use of the photo. As in, Cameron Diaz is not pleased with her Wikipedia pic and so she hires a photographer to do a shoot and release the best photo under a Creative Commons share-alike license, so that it can be used by Wikipedia. The photographer is compensated accordingly. Is there a problem here I am not seeing?

Well, how else do you propose to run Windows software on Linux? Win32 is closed, and wine would have to replicate all of its bugs to substitute it. We would need Microsoft to start developing its software for Linux as well, which likely won't happen no matter how much marketshare we get, and of course there's also the issue of getting that marketshare with zero marketing and the issues you discussed. I suppose that the low level API's could be robustified to increase adoption of Linux as a platform for high-end media content development, but the compatibility issue would persist. Bottom line, wine is not cheating, its the only hope we have of running Windows software on Linux.
