OK what seems more plausible: YT is banning people simply for watching a live stream that they are hosting, or that these reports are mistaken or part of a disinformation campaign by a country known for them.
The most plausible explanation I've seen is that Youtube's reporting algorithm is being gamed. It's a known weakness that Google has had no interest in fixing in the past.
Given what we know about YT’s gameable enforcement mechanisms, probably the former.
One report came to me personally from a small local IRC channel (less than 100 people) from a person who's been around for years. I trust them 100%.
