The British Broadcasting Corporation (BBC) is, as far as I know, a fully government-subsidized British TV channel. Does that not make it an arm of the British government? While some may point to its independence, the same is claimed for the US judiciary system. Yet no one claims that its independence makes the US judiciary something other than a branch of the government. The BBC is an entity which was founded by the British government, which is funded by the British government, and which at times (most notably during WWII) was a propaganda arm of the government.
Since the Russian channel RT (formerly "Russia Today") was recently asked to register as a foreign agent, because it is owned by the Russian government, shouldn't the same be requested of the BBC? Is there any distinction?
While it may be tempting to point to the fact that Russia is at odds (to put it mildly) with the US and GB is an ally, I don't think that British agents (of other branches of the GB government) are excused from registering as foreign agents. So what's different about BBC?
