the general rule of thumb is, don't base critical parts of your business or personal life on third-party cloud products that may go away for whatever reason, without your control and without notice. this includes Google's random termination of APIs, encrypted email services, etc. have a plan B if for some reason the Tor relays need to be suddenly taken offline, forever.
Unfortunately, some jurisdictions don't allow sufficient customization of corporate charters to do this yet. It's been getting a bit better recently.
