It was using IPv6 in IP, just like 6to4, protocol 41.

I haven't heard it called a political issue before though. It just had problems, like being blocked in firewalls and security problems where the encapsulated packet wasn't checked properly, etc.

«We forbid you to go right because we are going left.» It doesn't look like a technical issue. How I should call it?

Right. Neither am I, so take this with a grain of salt. But I'd use "committee decision" in this case.
