I don't know about everybody. But for those leaving X (Twitter) for “bluer skies”, I've heard that X has too many bots, the block feature is STUPID because Musk allows the person to see your posts even though you blocked them which is tantamount to allowing a stalker to continue to stalk you, and Musk is using Grok to steal your intellectual property (scrape ideas from your posts).
All of those reasons seem believable. I have had BSKY account since it started. I wasn't active. But someone on X asked me to join them on BSKY. So now I am slightly active on that platform.
No matter for me. I'm OK with X or BSKY. It's TruthSocial that I have a problem with. LOL.
