Yup, and afaik bluesky is just another corporate competitor to Twitter, so migrating there would still leave users vulnerable to the same basic hazards of Twitter, namely that they're still at the mercy of the whims of some CEO or board of directors. It's just a hope that those "leaders" are better, and will remain better.

The right wingers demonstrated the folly of that when they tried to migrate to parler only to have passport info and all kinds of shit demanded, STILL get censored by their own fellow right-wingers, and eventually had the rug pulled out from under them.

There's no reason to place your trust in a centralized corporate entity. Better to have something like this, with a good (not hateful) community and multiple points of redundancy. If lemmy.world went down there's tons of alternatives that take literally no effort to migrate to, if you don't like the moderation (or lack thereof) on one instance you can easily move, etc.

Granted, I don't use Twitter so I can't judge the relative ease of use, which I reckon will be the main factor for most normal users, less-so for someone already on Lemmy since that seems to self-select more for tech savvy.

I do know that the transition to Lemmy was very easy for me, and if it doesn't already exist a dead simple instruction post could be written up to get people up and running within minutes so long as the author doesn't bog the reader down with too many choices (ie, just suggest one good-enough client for Android and apple each, point people towards lemmy.world and don't confuse people with all the various instances, and let them expand outwards from there organically as they get the lay of the land).
