Good news, it looks like federating is still in fashion. Flipboard has starting federating a few of its publisher’s accounts via ActivityPub, and Threads seems to be actually following through on its initial promise - I’m actually a little surprised - and is at least testing the feature.
This is a controversial move to some folk, especially with regards to Threads. Personally I think it’s a absolutely a good thing at least in theory. But it’s surely not risk free. Undoubtedly one needs to do what one can to avoid any new federating instance successfully following the infamous path of the embrace, extend, extinguish strategy.
