If they invent their own protocol it’s probably going to take another year or two before wee see a usable implementation tho, the core components of Bluesky are closed source, well and Threads should be a activity pub app too but I have my doubts if they will ever implement it tbh!
Yea, I have my issues with Lemmy too ever since the Israel/Palestina conflict got violent again so my by far favorite and most used is Mastodon, to me that feels like a supirior Microblogging site that actually dose things different and doesn’t just try to reimplement Twitter!
