The joke of course is just how much content on YT clearly
violates copyright but just sits there for years. I mean entire major motion pictures
will be posted by some non-rights-holding Joe Shmoe, remain up for years, and get recommended
to you by YT's algorithms and have ads run before they show it to you. So you
go ahead and post a short clip from, say, The Jackie Gleason Show from 1960, Jackie Gleason Enterprises sends in a DCMA by the next day, it gets taken down, (fair enough) and YT has the absolute gall
to send you a "you're a naughty boy!" email and ask you to watch this oh-so-amusing copyright drivers-ed film
which declares pretty much anything not 100% original content is a violation of the rules, while pretty much the vast majority of the content on the site does exactly that.
So the poor analogy is this: kids throwing rocks at the old factory windows in full view of the police. If the factory owner calls the police and complains, the kids are promptly arrested. If the owner says nothing the police gather a crowd around inviting people to watch the kids smash the windows, then mills through the crowd selling tickets to the policeman's ball.
