I’m positive at least some of the servers that house Lemmy and its FOSS sister networks are housed in VC companies. The amount of people who can support that data and the servers it resides on is small without Corps being in the mix.
We’re not exactly winning over here on Lemmy or Mastodon. I’ve been a member of the Mastodon community for close to 6 years or so. It isn’t a reasonable replacement for Twitter because (for what I used it for, which had nothing to do with Micro logging), it doesn’t do what I need it to because the number of people I want to follow there are few and far between. Bands, book authors, local news networks, international news networks. I’m not likely to find out about school closings on Mastodon.
Anyone who knows how good we function in a crisis is able to extrapolate from there that this would be a thing.
As others have said it’s the burnout and the subsequent time it takes to recover that makes this basically unsustainable. Even when finding a balance there will still be burnout.
