I don't know, I always view these "fork of X without developer fee" thing as a little… well, shady, to be honest. The point is, that everyone wants to be rewarded for their hard work. I get that, and I think it is totally legitimate. The question is: How much is enough, how much is too much? That's a difficult question without real answer.
But any way your stance on developers funds is, here is what bothers me about those forks: they are inherently parasitic. I'm not saying that it's a given and that every single one of them is that way, but don't you think ,that once Zcash implements a major improvement, Zclassic will copy it? And don't you feel a little uneasy about it? I certainly do.
The thing is, I don't want to live in a world, in which original creators are not getting paid for what they come up with. Because 1.: if they don't get paid, they might stop working on new projects and improvements. You can't eat fame. And 2.: they might decide to work for people (or rather companies) that are willing to pay them. Personal ethics only got so far. They might stop at an empty fridge.
EDIT: I forgot 3.: it feels right. seriously, everyone is getting paid for their jobs.
So, I think there has to be some system in place to reimburse them for their hard work. In a perfect world, a donation based system would be perfect. But people are greedy. I get that.
Apart from all that, instead of a fork, I'd rather see some original ideas coming up, going at the same problem from a different angle. I try to think about something like that aloud here:
