Same as when one of the big name hosting companies takes a site down. You hope it’s archived, and if it was important enough to you, hopefully you saved it to your personal server.
What you’re describing is a major benefit of federation. Any site can be taken down. But when a federated server goes down it’s because the site owner exercised their control over their own data. If Google or Amazon takes a site down, you lose your data, but they keep copies to use however they want.
The obvious question to me is, what did he do with his money?
He sold his house for $300k when he moved into the governor’s mansion four yars ago, but he didn’t keep the money from the sale? He has an upper middle class salary, but no savings?
Either he’s got a bunch of credit card debt to pay off or a drug habit, or he keeps his savings in cash under his mattress. But money doesn’t just vanish like that.
