I was somewhat optimistic about this app given that they were embracing federation, felt like an important milestone like when AOL had to stick a full featured web browser in their app. But this is just gross. Don't want to be a data slut for Zuck.
Any big major for profit company embracing federation is purely for their own revenue generating goals and have no explicit want to be actually good stewards of the Internet, its communities, and about their participation.
Participating in Federation is another way for Meta to suck up as much data as it can to sell its advertising services.
