What examples could you give as to how this would be a bad move?
Look at big game companies, they recognized that they hold a huge fanbase thanks to certain franchises, some even go back to the 20th century. Success corrupts, most great game series ended up being repetitive, crappy, rushed money makers.
The other side of the situation, is the so called MMO market. Look around, you see the "success" and "popularity" of the F2P, P2W approach, which is disgusting for any gamer with some common sense.
This is why I said, "success" is relative.
Also, you might as well just forget what I've said, the cRPG developers would need their own engine, own game, own everything, to ask money for their work. Donating is a totally different story.
