Did those users not hear they can dodge Age Verification by using a different Bluesky compatible app?

And beyond that, it’s not like you can’t migrate to Blacksky or another third-party PDS, or even host your own PDS if you have the hardware and admin chops for it, although you can also self-host on the Fediverse too, and there’s thousands of instances on the Fediverse vs. a handful on ATproto, plus other than Blacksky who are supposedly completely independent from Bsky’s corporate infrastructure, most third-party PDSes and pretty much all self-hosted PDSes still have to interact with Bsky’s corporate infrastructure at some point where if you host a Fediverse instance, you own the whole thing.
