Apple I think is a good example. It only mattered to Apple when it cost them a non-significant amount of resources. Ultimately they are a company and they respond to profit, if people buy or don't buy the product then that's the strongest fact that will influence them. Also I think it is a misconception that GNOME has a lot of money from Red Hat. They don't really from what I've seen, most of the Red Hat people I know are pretty strapped for time. I also have no idea what you mean by forced it as default. Distros don't have to choose it, I've seen many distros that choose other things or just don't have a default. If you mean things like Ubuntu, IIRC they chose to retire Unity and go with GNOME because Unity wasn't profitable for them. So with companies it always comes back to that...
I also don't really think it is useful to call out people for imposing their vision. On a certain level, everyone who builds things is doing that. They have their point of view and that's the only thing they can express, because well, what else would they express? If they expressed your point of view all the time, then they wouldn't be themselves, they would be you. It's possible to change someone else's vision but that's usually done by presenting new information, i.e. convincing facts.
