I’ll edit this comment when I get to my computer to link to a great article about this and a history of companies effectively killing federated services .
Edit: article here https://ploum.net/2023-06-23-how-to-kill-decentralised-networks.html
But the main issue isn’t the data. It’s that when 99% of the users are coming through a company, they have too much power when it comes to updates. Meta can effectively control how the fediverse grows. And if they decided to defederate it’s the normal Lemmy and kbin users who are forced to use meta services to keep in contact with the same people
I didn’t care nearly as much till I started working at a company that is 100% apple only.
That said, I try to keep my complaints focused on things I found aggravating.
