a replacement for X, signals a Temp/emergency solution, not a new market, if that's the driver with Threads, they've lost it already.

tech-giants are so powerful, they don't have to move-fast-to-break-things, a small tantrum/jitter (e.g Musk-twitter, or rush-to-replace) can mess-up a considerable part of the ecosystem around them; including their own finances.

happy to try it, out of curiosity.
