I don't think "the market" has internalized how risky the US is becoming, and I think it'll take somewhere between a few more months and a few years for that to happen.
It's not just about chaotic dumbassness like tariffs. It's not just about disrupting the labor force for stupid reasons. It's not just about attempts to undermine the independent management of the monetary system. Those are bad, but worse is that the whole underlying system of institutions is being trashed. Random shakedowns are being normalized. Government (including courts!) is being deliberately packed with partisans and cronies.
For a really, really long time, the US has been a place where you could expect your counterparty to perform on a contract, and if they didn't you could expect the government to come to your aid, no matter who they were and even if you were a foreigner. You definitely didn't expect a "personal tax" on your company if you didn't suck up to the right people (or just because you happened to be handy). Oh, and you also didn't expect to be dealing with the kind of people a system like that selects for.
People just assume the US isn't run by gangsters, like they assume there'll be air the next time they breathe in. They're so used to that high trust that they don't even consciously factor the question into their decisions. It takes a long time for that kind of mental habit to change. It doesn't happen in a few weeks or a few months. But if US trustworthiness goes away (which it seems to be doing), and people figure it out (which they eventually will if it keeps up), then they're going to start assessing risk accordingly.
Admittedly some of the random stupidity and even more of the outright gangsterism seem to come from Trump personally. He's 79 and in theory he only gets 4 years regardless. But that doesn't mean that it all comes from him, and he and those around him are trashing institutions and norms really fast, in ways that are really hard to repair. It's a big gamble to assume that can or will be reversed by a successor, especially since the systems that are supposed to choose that successor seem to be being rigged to favor candidates with similar approaches. And it won't help you if you're out of business before then.
Bluesky is private but the underlying mechanism is OSS and accounts are portable.
Go build the replacement and people can port their accounts across.
Maybe you could theoretically have an AT "app view" that takes data from multiple relays, but nothing in the implementation does anything to support that, and as far as I know nothing in the protocol does anything to help it discover the relays... which in practice means that even if you extend the app views to use multiple relays, there will never be more than a handful of relays with meaningful reach.
The AT protocol is at best a really crappy excuse for decentralization. And frankly a pretty poor example of open source too, given the usability and organization of the code they release.
Compare with, say, Nostr, which is actually decently decentralized... but, in not-unrelated news, suffers from massive content discovery problems. Or compare with Briar, which is even more decentralized but has both discovery and scaling problems. Or for that matter Usenet.
