There's a very real and dangerous trend towards extremist positions as a result of social media bubbles. I'm sure most people have noticed how large family gatherings have shifted over the last 15 years, and how some family may no longer even be invited as a result of social media driven shifts.
The fediverse makes these bubbles so much worse, with servers of like minded moderation creating a trend towards groupthink as opposed to representing a variety of opinions.
So while it's promising from a standpoint of shrugging off corporate driven issues in managing social media, the fragmentary nature is perhaps the opposite of what social media actually needs, which is less bubble driven optimization with regression towards extremist means and more broad exposure and interaction with regression towards the normal mean.
