After reading Mitchell Baker's "deplatforming isn't enough" rant pushed at me by Firefox, I expect nothing good out of Mozilla under the current leasership, sorry.
This really is the kind of thing that could uncover some very shady practices by Facebook and others, but I expect it to produce the same kind of bullshit as the recent "Facebook whistleblower" who worried that facebook is not abusing its power sufficiently to censor and unperson people.
