Everywhere I look there are people advocating for defederation from this and that! Do you even understand what you’re suggesting? Do you get what’s the point of decentralized social media and activity pub?
This is supposed to be free and accessible for everyone. We all have brains and can decide who to interact with.
If meta or any other company manages to create a better product it’s just natural that people tend to use it. I won’t use it, you may not use it and it’s totally fine! It’s about having options. Also as Mastodon’s CEO pointed out there’s no privacy concern, everything stays on your instance.
I would have phrased it as “supporting” Threads. If you don’t defederate, Threads will take over your instance. Either directly through the sheer amount of posts, or indirectly by colluding with your instance admins. Or both. It’s how they operate. And then the ads and data harvesting and walled gardens will come.
