I suppose I'm curious if you'd really welcome Chrome and Edge to a Fediverse environment, the way you're speaking to Mozilla. Especially as Mozilla walks back from their Fediverse investments.
I would wonder at an incentive structure that would make Fediverse a good idea for Microsoft, Google, etc. In a sense, it could be a way for them to pull influence away from a competitor, i.e.: Meta
I also wonder if Microsoft would ever want to allow federation for LinkedIn.
