Quotas are not the only way to combat discrimination, nor are they a good one. Name-blind hiring would resolve name discrimination without making additional presumptions about the applicant pool. A quota presumes that the applicant pool has a particular racial mix, and that a person’s qualifications and willingness to apply are independent of race. And even if those happen to be true, it can’t take into account the possibility that the random distribution of applicants just happens to sway one way or another in a particular instance.
Why do you need so much info on Mike? Can’t you just evaluate his statements/work on its own merit? The whole point of open source, federated platforms is that you don’t have to trust him. If he decides to enshittify it, you can just go with a fork or another instance. A nomadic identity isn’t a centralized alternative to the fediverse, it’s just a way of bringing some of the features of a centralized identity to a decentralized one (at least, that’s the way I interpreted the article).
