I am seriously restricting my inbound and outbound reach by boycotting X. It's a hit I can afford to take, but for some people they'd be making a very foolish choice when that's where their audience and the content they want to read is.
NPR's audience is very different from mine (AI researchers and thinkers) though. Some communities seem to have managed the move wholesale: all the cartoonists I like switched, for example.
By the time I left I was deleting multiple bot followers a day. You cannot take X's claims at face value, everything about the platform is aggressively dishonest. NPR's experience is instructive: https://niemanreports.org/npr-twitter-musk/
I don't think it's realistic to pretend that abandoning X is seriously restricting anyone. If anything, sticking with it is brand endangerment and by leaving it you're making the smart move, with or without animus.
