I have done a little bit of reading but I’m still not sure what the issue is. Is it that Threads will take over and defacto become the entire Fediverse? Because I think that would happen whether or not Mastoson/Lemmy instances choose to defederate. Is privacy the concern, and if so, wouldn’t it only affect people using Threads?

One concern would be:

Say Lemmy/kbin grows organically to 1 million users.

Threads federates, with 100 million users

Do you want these users flooding Lemmy? I don’t want to be biased at the theoretical type of user on Threads, though if the right wingers/trolls/extremists migrate to Threads because they think it’s “more open” then that may be an issue. If it’s full of soccer moms posting pictures of their kids, or karens complaining about everything, that may be an issue.

Multiculturalism is great, I want to hear new ideas, though some areas are breeding grounds for lower-think, it seems. This probably sounds prejudiced or elitist.

I want to talk to the vanguard people who take the risk and are openminded and come to lemmy, not necessarily the “lemmings” who join facebook because they love facebook and don’t want to, or can’t, delve deeper into why facebook is one of the worst forces in media at the moment.

I donate money to this platform because I want an open and free internet. I want that for anyone who wants to partake. I don’t want extremists, sure - but I think the “soccer moms” you are referring to are really just your average internet consumer. If we don’t agree on that, that’s fine - I’m happy to move to an instance that’s not as restrictive. I think that’s the beauty of the fediverse. I think it’s ironic when you talk about wanting open minded people to join the instance though lol.

I have nothing against “soccer moms”, I just don’t want to see endless photos of their kids, which may be ironic since there’s shitposting on all social networks. Perhaps we’d be able to ignore those communities, however it’ll leak over to other communities.

It seemed to be “fine” when “those” sorts of “regular folk” stuck to facebook for their fix of sharing their lives.

Anyway, this aspect isn’t the main point, I’d say - it’s that one cannot trust facebook, and if they want to federate, it cannot be good for us.

Personally I don't care about the soccer moms, my main concern is all the problems that come with being a mainstream social media platform. Threads threatens to overwhelm the content being generated with all those problems where you Lemmy feed is just going to represent Instagram etc again. Screw that.

That’s exactly what I’m talking about when using the generic “soccer moms” - mainstream twitter/facebook posts.

I’m probably confusing myself as I have nothing against “normal people”, and want them to discus sthings, and I’m sure there could be a lot of good discussions that could be had with “normal people”, though being drowned by mainstream media posts is the main issue, as you say.
