Ahem. Excuse me.
First. You talk as if you don't care about either the artists or the people who view their work... and yet here you are, ranting at both "sides". Stop talking bullshit and either be honest with yourself and those you're speaking to, or get back in the closet and continue lurking. If you honestly didn't care, you would have no opinion, one way or the other.
Second. You speak of saying who people are and what they've accomplished, but the best you care to do for yourself is say "you've been in the fandom from the beginning". You also suggest you might have been an artist at some point. Say who you were and show some examples of what you did, or once again, I suggest you just go back to watching and being quiet.
I've also been in the fandom from early on. I feel no obligation to tell you who I am, or what I've done or anything else about myself. I feel like the fandom is going very sideways, but I also feel it has to do with changes in who is a part of it, aging in general and boredom. As for the artists simply dropping a project...? That's up to them as always (unless they've been paid, and even then it only has to be shown to the one who paid for it).
The simplest solution to incomplete art is for people to stop stealing it so damn much the artists throw up their hands and say, "Fuck it." then go find some other hobby to enjoy. At the same time, artists need to recognize that if they want to actually have some sort of fandom, and not simply be "that weird guy who draws animals having sex", they need to cater at least a little to the fans... that means affordable prices and at least some free art for people to look at once in a while.
Simply put, the fandom is slowly falling apart, even though I remember a time when the fans claimed it would outlive everything. It's sad to watch, but it has a sensation of inevitability to it as well. There's no point in making things up, nor ranting at people who couldn't give a rats ass if you say something, so your post is kinda pointless... not to mention it feels fake. Just let it go.
