There seem to be many ‘sources’. Youtube have a policy where you can show explosions, you can show guns shooting as long as you can’t see the targets - it’s clearly written. Yet several people are demonetised for showing clips related to Ukraine for a start - and YouTube doesn’t respond to requests to explain, it’s a secretive policy that doesn’t follow the written policy.

It’s also very easy to find other videos which would more clearly break the actual rules as they are written. Basically, they do have an agenda - it applies to many similar channels - and they keep very quiet about real reasons for doing so, instead quoting some bullshit rule which isn’t true, and doesn’t apply, both at the same time.
