Meta threads will open federation to the fediverse soon, and while this is mainly to mastodon it will still affect lemmy. They are acting like they won’t be evil, but let’s be real this is Facebook when have they ever done that.
This article which has been trending lately explains some of the issues. https://ploum.net/2023-06-23-how-to-kill-decentralised-networks.html
This comment here is a simple analogy if you can’t be bothered reading the article. https://lemmy.ca/comment/5702922
Why would anyone join Lemmy/Mastodon if they could join Threads instead for the same content? Normal people don’t care that your shit is FLOSS or decentralised, they just want convenience.
Why would anyone run their own email server if they could just use Gmail instead for the same content?
Your argument could also be used against the very idea of federation.
Gmail killed the popularity of most email services. Don’t let Threads end up like Gmail
