Smart…well damn, if they’re that blasé about it I’d consider it a public service to escalate. You could contact Microsoft’s legal department, they might take it more seriously
You could also reach out to an organization like the ACLU in your country, they may or may not do anything with it, but they’ll probably make note of it at least. It could push them to take action in the future
FWIW, I respect you for going this far, and doing so intelligently. It might just be a little thing, but it’s fighting for your rights. Every inch matters, because they’ll take them all from us if they can
