Sure, it's easy to see MS behind this kind of stuff.
But Microsoft gets sued, too, and for example the latest stuff from Europe clearly has Opera et al pulling the legal strings.
It's just the way things are done.
PJ/Groklaw have been tracking the Psystar psycho-circus and it does have some similarity to the MS-funded SCO/Baystar anti-Linux stuff. I fully expect MS is behind Psystar in some indirect fashion.
My only question is, how does Microsoft manage to consistently choose such badly-run, psychotic, stalking-horses?
I don’t think Opera is lurking in the shadows though are they?
