I'm a bit the wrong receiver for that kind of information. I'm not on lemmy.world but run my own instance. I've donated days worth of developer hours already, and I'm planning to do more... But I can't speak for other people.
And I dislike money being involved. That leads to obligations, envy, and people stop doing it for the fun and because it's a nice platform. I think that shifts things and I'm not sure if in a good way. We'd get closer to commercial interests and we already have enough commercial platforms. I liked the old way how Free Software worked. Some random people doing it out of their own motivation. Coming up with all kinds of interesting software that'd help them. And they'd generously share it and invite everyone to participate. And it'd stop there. No ulterior motives involved.
But with that said, yeah. Someone has to do the development, pay for the servers and do the community work. That's not optional. And we have a broader issue with money in the Free and Open Source ecosystem.
