I think they're making a move on Twitter. They smell blood in the water, Twitter's weak, not worth buying, but worth supplanting. Here's the Fedverse with a ready-made platform, so no use re-inventing the wheel. They don't care that it's the Fedverse. They just want the interface, to build a replacement.
If Reddit keeps being stupid they can expect the same treatment.
But truly, I know nothing and speculate wildly on most subjects. And I'm new here and understand nothing about the Fedverse.
