Every time something like this gets posted, there are always Lemmy users crying to defederate their Lemmy instances.
But remember, the current concern is with Mastodon, NOT Lemmy. Lemmy can’t actually view the post types that Masto and Threads make. Wendy’s can post all the Threads ads they want - we’re not going to see them here. We can’t. That hasn’t been built.
Try it. Go view someone’s Mastodon account in Lemmy. You don’t see their posts.
@Ghostalmedia
It has been partially built insofar as Kbin and Mbin can see Mastodon posts here and Mastodon interacts with us. Wouldn't surprise me if Lemmy eventually gets some of that functionality too.
If Meta starts to EEE ActivityPub that will affect all of us.
To illustrate even more: I follow a Lemmy privacy "group" with an Akkoma account.
You will in fact see their posts if they reply to Lemmy comments. They'll then appear as comments in Lemmy. I believe Mastodon users can also post to communities by using hashtags, though I'm not 100% clear on that.
When you @ mention a community from Lemmy as a user on Mastodon you can post to that community from Mastodon. The first sentence of your Mastodon post will be used as the title, which is why they often look so strange on the Lemmy side.
You can also follow a Lemmy community from Mastodon, but it gets a bit messy as every comment will be shown as a boost Mastodon side.
I hope the groups addition that Mastodon is working on will fix that mess.
I post stuff on lemmy via my mastodon account so I don't have to deal with image hosting on my lemmy instance, so its not quite that simple. You're not wrong, but they do interact
@Ghostalmedia @deadsuperhero I think the fact that I was able to see and reply to this comment of yours from Mastodon proves this idea false, if you check the Post history of this account you will also find that content posted in Lemmy is visible.
They absolutely do interact, lemmy is way more Mastodon friendly than most people give it credit for, considering the fact that communities/groups, automatically boost every post and comment for visibility.
So people on Lemmy being concerned about poorly moderated or cesspool microblog instances is indeed a valid concern.
It's not us seeing Threads that's the problem, it's Threads seeing us (and thereby trapping all of us in their sticky web we tried to escape, what with their shadow profiles and whatnot).
So what would stop them from shadow profiling you by scraping content, or using a different domain? Most lemmy instances are configured to federate with a blocklist, meaning any unblocked instance can download data. Facebook can just make an instance under a different domain and download the data that way. Or they can just scrape user data from the web facing interface.
Posts and comments on lemmy are public. If facebook wants your publicly accessible data from the fediverse, de-federating from threads isn't going to stop them.
