For my own part, I support breaking any artificial borders on the Internet as well. But rather than adding a restriction like "can't do business with a company if they offer different services to different locations", I'd instead remove any restrictions that might affect someone who simply purchased the service as provided in a different locale. (The company can try to block accessing other versions of the service, but that's a technical problem, and solvable with a technical solution. If the company can tell where in the world you are, we haven't made the Internet good enough yet.)

For that matter, geographical restrictions on media depend on restrictive copyright laws to have any effect at all. So I don't support adding a restriction to "solve" a problem artificially propped up by another restriction.

If the proposal on the table was a law/treaty to prevent people from accessing the service as sold to a country other than their own, then I think we'd both agree that's a bad idea and oppose it.
