Great points.

I always thought that the deplatforming of popular people was not only an idealogical selling point but also a giant arbitrage opportunity. 

The biggest component would then be having someone with the charisma and energy to onboard that popular content creator and their audience as quickly as possible while the iron is hot.

Not sure who would be a good candidate. Could be a tall order but I think slick UX for normies + talent on the persuasion/onboarding side could go a long way when those opportunities present.
