The 09ers and the 10ers haven't really done collabs as much as older ones. Yes, 09ers have done a few collabs, but older animators have been doing collaborations a bit more. Truthfully, collabs may be overdone these days, leading to the loss of many solo animations. There are still full tributes being released, but the quality of it is lowering. You may have a point, but you're not completely right.
I feel that most people are leaving because they have gotten bored, wanted to stop or would like to try something else. Some of them go unsaid, and some of them surprise us with comebacks. It's not just one issue that caused people to leave.

Lol in your last post you worried about everyone leaving, well the seniors just left cause the 09'-ers fucked up the genre by turning it into a booring collab factory. Fact!

the collabs didnt ruin everything in madness if thats what you mean, you can choose between, joining or not, you can like it or not, you can vote 0 or 5 if you like it or not, you can choose between doing a collab, doing a serie, doing your own sprites, doing your own plot. You cant make someone guilty for doing something that doesnt affect anyone, because people can choose you cant be guilty for doing something you like. You don't depend of other people to make something, you can do it yourself, so you can't say that they fucked up the genre cuz they make collabs, they have people that likes it, and people who don't can do what they want.
