That's a redundant question, because just about every registry can dictate what their TLDs can be used for. It's part of the design laid down by ICANN. - For Verisign with .com, they don't care if you're really a company or not. - With Minds & Machines and .law, they only want qualified lawyers, courts, legal schools, etc. using the TLD. Keep in mind that the registry and registrar are different things.
@bduerst, Forgive my ignorance, but just to distill it down to brass tacks: In this case, Google is the registry and thus the supreme court of who can and cannot be on this domain and there is no recourse if they yank your claim on the domain? Is it more nuanced than that?
IME you're much more likely to be banned by the registrar than the registry itself. Registries want people to use their TLDs, so they're not going to reject post-registration unless you've changed how you're using the TLD and it's violating the rules they originally laid down. Registrars are much more consumer facing and will act accordingly - i.e. GoDaddy banning Gab.
