Agreed. Just look at Twitter. It's running with a skeleton crew but that's only because a system of that size does not collapse in a day. It takes years for the cracks to show and grow.
This can't be posted enough. Twitter currently employs 100x more developers than Mastodon. It's comically incoherent to claim that people should move from Twitter to Mastodon because Twitter obviously can't be run by half or a third of the developers that it used to have, because scale or something.
