The argument is about how it is illegal, and the SFLC complaining to governments to fix this. If they force MS to license their software to any OEM, they should similarly force Apple to license Mac OS X to Psystar and also unlock the iPhone and iPad's bootloaders.
It's not about forcing companies to license their software; it's about forcing companies to allow unlocking of the bootloader, thus forcing them to compete on features rather than antifeatures (consumer lock-in).
Locked bootloaders on general purpose computing devices are bad news for consumers and for innovation in general. Just imagine how the PC landscape would have evolved without clones. I'd be more than happy to see government intervention in cases like these.
1) Two wrongs do not make a right.
2) Both are worthy of criticism.
3) What Apple does is off topic anyway. This discussion is about Microsoft.
