I get what you mean - if the developer stops supporting the game then they might run out of money to make the changes. This can even happen spontaneously in some cases. But I'm still expecting at least some effort in preserving their product, their legacy. Some people might call it naive (and it probably is), but for me personally the baseline is that games should be playable at least in some way. Maybe the experience will not be the same, maybe there will a lot of lag, maybe something will break. But it is still better than not being able to play the game at all.

I don't think anyone is downplaying the effort of making a videogame that is both easy to host for the small developers and for the community. But unfortunately developers themselves often choose to pursue financial goals disregarding everything else. So it's understandable that gamers are not happy and demanding some solution. And that the industry is trying to push back.
