At the very least, he deserves several decades as a junior janitor in the Bhasan Char refugee camp (with full asset seizure) for his contribution to the Rohingya genocide. A similar rehabilitation approach should be applied to multiple other Meta executives as well and the whole board of Meta.
And when I say "asset seizure", I mean every last cent, with all family members and business partners being forced to sign affidavits agreeing that should any assets be found and there is reason to believe they were involved, they'll have to partake in the same rehabilitation program as Zuckerberg (including affidavits for their family members and business).
It's a scalable and efficient approach to justice.
