While he certainly wasn’t sensitive about how he said it, he did state is was sanctions related.
He was not clear on that at all. For all we know it could be an excuse among the several vague ones he gave or a reference to pressure from Feds.
And FYI for the actual innocent bystanders who aren’t troll farm accounts - the “various compliance requirements” are not just a US thing.
If you haven’t heard of Russian sanctions yet, you should try to read the news some day. And by “news”, I don’t mean Russian state-sponsored spam.
