So I think user deng has a point about “selling out” still being a thing.
That being said, I think there is a big difference between selling out and wanting to remain in control of your creation. I have no idea whether George Lucas likes what happens with Star Wars or not, and I hope I’m not going to start a debate over it either, but by selling it he lost the creative control in a way the Bill Watterson didn’t.
My guess is that being “seen” as a “sell out” isn’t actually something that comes into play when people consider what to do with their creations very often. Because honestly, why would you ever care? So maybe there is less of it today, but to state that our public discourse has changed on the subject? I’m not convinced it has.
