Yep. Apparently the entire fiasco traces back to him; he's also been attempting to push a number of other idiotic ideas down everybody's throats, and not surprisingly he has been met with quite a bit of resistance.
Basically, the story behind that is that there was a technical note released by Apple that was basically commanding developers to do things the NeXT way. Use Objective-C and never use C++. Don't use file type and creator type. Only use Mach-O binaries; if you want OS 9 compatibility, make a seperate CFM binary (despite the problems this can easily create). Blah, blah, blah. Supposedly Tevinian wrote the note, but it didn't have an author on it. In any case, Apple withdrew it within a few days due to MASSIVE negative feedback.
