@atomicpoet As they're just selling you hosting, is this really a big issue? They don't own your data, you're not locked in... Aren't those the big issues? As compute becomes more of a commodity, isn't it good to just have someone else deal with that and put the effort into higher value things?
I'm still not very settled on this but it feels like controlling your data and moderation are the bits that commercial social media can get very toxic with.
