I feel the post doesn't really address my concerns.
Really? You think Threads will take over and rule Mastodon? Threads is its own platform, users on the fediverse can still join Mastodon #servers of their choice and leave. I expect we'l see plenty of anti #threads Mastodon servers pop up. If Threads were to somehow get an influence in Mastodon, just switch to #lemmy switch to #pixelfed switch to #firefish So many choices.
This seems to not really understand the risk Threads poses. Threads is its own platform, yes, but it will dominate the visible content of any instance that federates with it. It's very dangerous to depend on a massive, profit-driven corporation for activity on the fediverse, as the things we value on the fediverse (decentralization, transparency, even distribution of content between instances, etc.) go against the corporation's motives. Meta does not stand to benefit from any of the things we value, and most of the Threads userbase (i.e. casual Instagram users) probably won't notice or care about federation. Meta does benefit if everyone depends on them for content, as then they can pull people to Threads just by defederating. People will choose to go to Threads where the amount of activity is what they're used to over staying on their Mastodon instance after activity has plummeted and they can't see most of the people they follow.
This is a big one. Meta might capture the mainstrean fediverse. Lets just be real the average regular internet user wasn't going to join Mastodon in the first place. Not that they wouldn't want to it just isn't on their list next to #facebook#instagram#tiktok#youtube#discord or even #twitter . Actually I take what Meta is doing as a compliment to the fediverse. Remember Twitter at one time under #elon#elonmusk banned the talk of Mastodon or something like that. Threads might not have our interests at heart but they are already mainstream so why should they not allow their users be federated with us?
Yes, there are definitely a lot of people that the fediverse is just never going to appeal to. But of those who are interested in the fediverse, more will be inclined to join Threads due to it having most of the content & just requiring an Instagram login. There is a pool of people out there who will try out the fediverse if they're introduced to it — that's how we all got here — and if people can interact with the big Mastodon, Kbin, etc. instances from Threads, many will choose to do that when they wouldn't have otherwise.
