I think this is like a parallel situation as seen in the Reddit ceo driving migration to lemmy.
The wp meltdown was destructive and healthy at the same time. A minority of wp users will look into alternatives, which will help make those better to use because the devs get more support, and/or the alternative communities and ecosystems start to grow
Maybe lemmy will grow over time to include more types of people.
Social unrest may evolve this network faster than expected, in particular ways that are not foreseen. So, in my mind there are two paths for lemmy. A stable growth or chaotic .
Edit : unrest in any country that has a lot of lemmy users if alternative social networks clamp down or are unsafe to use
