I have concerns and there is problems but it has the potential for growth and making the Fediverse an legitimate actual thing may be worth it.

The thing about social platforms is that they really have to reach this critical mass to really be successful. After they reach that point they begin to self feed. Reddit did a huge user dump on to Fediverse/Lemmy but with things being so spread out and disorganized I don't think it reached that critical mass. If Fediverse didn't your likely to see a 80%-90% return to reddit. A user dump from a company like meta would likely go far.

Proper admin tools for both the instance and the user could go far.
There will be growing pains no matter where the source of the growth is from.
