I actually don't think it's a useful distinction, since the topic is media, not media companies. SpaceX's and Tesla's social media accounts are media, and they're both as state-affiliated, if not moreso, than NPR

folks reading posts by Tesla and SpaceX should know that aside from elmu's history of disingenuousness and outright lying, such posts are even more likely to be pro-government biased than NPR

so I agree: SpaceX and Tesla should be labeled according to the government which supports them, there's no shame in that.
