Sorry misunderstood your comment, yeah Threads/Meta is god awful for collecting data wouldn’t want to touch them personally
There definitely is money in it for Meta though, just yesterday there was quite a popular post showing the types of data that is available to both users and instance owners. If one wanted to they could use things such as your upvotes and down votes to build a sort of profile about you, your political affiliations, interests etc
Meta isn’t just a problem, ad companies can easily set up an instance to start collecting data from other servers
