Exactly, and that’s why the response has been so negative. Every instance that federates with another stores a complete copy of the posts and comments from every federated user.
If the majority of instances do not defederate from a Meta instance, that Instance will inevitably become the primary destination for discussion, even between and by non Meta-Instance based users, just because the communities in that Instance will be so large and active. And even if they don’t, Meta Instance will have a stored copy of every community whose Instance is federated.
Meta will then have carte blanche to collect data on a huge collection of users from outside their own Instance.
I acknowledge that they could get the same data by scraping the public Instances anyway, but still… Fuck all of that.
This article is clickbait. There are exceptions for devices that are “waterproof” or have batteries that last a certain number of cycles.
This isn’t going to change a thing (especially it EU judges allow IP68 to be considered “waterproof.”)
