Purely from the operational perspective, you need to handle support, you need to handle billing, to handle lawsuits, to handle infrastructure, to handle incidents... and still have a good idea of what's going on.
So no, not sure it's happening.
You'd need someone who cares enough to make a point to a very niche community but doesn't care about the product enough to hire, and I think the two circles don't overlap.
... but if it did happen I expect it'd be a NSFW AI chatbot/companion, not VC-backable (or at least not openly)
There are some people building those that don't want or care about building the best product: they've realized if you get the cheapest most heavily quanitzed model around to produce NSFW content and tell a lonely person they're loved, they'll give you increasing amounts of money.
People don't generally spend $1B to prove a point.
They'll spend it on a network of users that is genuinely that valuable though. That's what Zuck did in dropping $1B on Insta.
And it seems entirely possible that if Insta were built today, it could be done with a single person.
Who has invested $1B+ in something they expected would lose money just to "prove a point"? And what was the point?
And Musk buying Twitter doesn't count because he was forced to buy it after it became clear he would lose money. He did everything he could to get out of it.
Software itself will not make people use it.
