You’ve been split into your own tailnet now and the domain has been marked as shared. Thank you so much for calling this out, and sorry again for the confusion.

I echo the other comments, this is terrifying. Security should be the default and treat unknown domains as shared.

You should definitely have to prove ownership of your domain to have it be treated as a company domain. This being the default makes no sense.
