Technical achievements aside, and at the risk of making devs feel bad about their great work, this stuff comes down to unmet expectations and broken promises. So much of the difficulties of federation are glossed over to the point that the image is that it’s all positives. Negative surprises are unappealing user experiences, especially amidst such an air of positivity.
Maybe we need to readjust our needs re social media. But that’s not and unlikely to be the pitch.
