I think it's pretty safe to say that the majority of us are here to avoid another corporate takeover of our preferred platforms. It would seem to me to be a tad irresponsible to allow Facebook into our space with open arms, allowing them to hoover up our data. I would love to keep using Lemmy.world, but will happily change instances if need be, and I feel many share that sentiment.
Not federating it seems like a weird choice. Can't each user block Threads themselves if they want? Isn't that the point of the fediverse? User control?
New users will look at lemmy.world before they create an account. They will choose to join after seeing threads posts and comments on the front page. The default settings will keep them looking at threads untill they figure out they can block it. But when they do, they realise that 90% of all posts and comments came from threads, and they just disabled most of the content.
I would be ok with an opt-in mechanism, where the default settings and the anonymous settings disable threads content, but you can unblock them.
why unblock? again, you're making the choice for them? Most people will use the Threads app and never realize that it's part of the fediverse... but SOME will and come over. The rest of the people already on lemmy or whatever, will just block it when it annoys them or they will engage and it will be fine.
Not with the way instance blocking works on Lemmy, unlike Mastodon which limits interactions from blocked domains lemmy doesn't limit interactions at all through user blocks, it just makes them not appear.
Combined with the fact that instance blocking doesn't even actually block the users from those instances. All it does is filter out every single community. If you read the page on join-lemmy.org it'll tell you that clear as day.
Like I said for both of these reasons user-based instance blocks on Lemmy should not and cannot be considered an alternative to defederation.
I believe that it is the same type of people that don't want stuff like infinite ammo cheat codes, easier difficultis or other similar options in games, because they think it makes it to easy and boring. If you don't want to activate god mode don't do it, but don't go acting like a completely optional thing, somehow is mandatory and required.
