First off, I can't believe YouTube described its content as "high-quality", because most of it isn't. Second off, what the hell did Google expect? They've been doing a piss-poor job at reviewing their content for years and even when they actually do, they don't do it because they want to make the platform more comfortable for kids to use or anything virtuous like that, it was to make the advertisers happy. So yeah, now the governments are involved, tough shit.
