Facebook has 3 billion users, probably 90% of Mastodon users are on one of their services already. The entire Fediverse userbase is not just less than a percent of their userbase, but less than 1-2% of their annual growth, it doesn't even make a dent in the first derivative
It probably doesn't pay for the Threads servers and salary costs if they vacuumed up every last Fediverse user. At the bottom of all these EEE conspiracies is always a completely inflated sense of self
This seems like a terrible play given how small the fediverse userbase is.
The whole boondoggle is happening because many Fedi instances are ran by those very same enthusiasts. They chose to settle on Fedi for various reasons, and I’m pretty sure Meta transgresses most of those reasons.
Personally, I don’t care too much whether my server federates or not, but I’m a very casual user.
