I think you've got it backwards. Adobe supported running CS6 on various platforms. The platforms weren't (and aren't) the ones doing the support.
At this point, no one supports CS6. The fact that you can use it on some particular desktop platform is partially a consequence of their past support, and partially because the platform hasn't "shifted out from under" the application yet.

I don't think that reflects reality. I would suggest taking a look at the internals of AppKit and other critical paths, you'll discover they are very aware of the applications linking into them.
