I don’t know how an Anti-Corruption office would go with Media Outlets spewing misinformation, free speech is fundamental after all. If they say something that’s wrong they should be sued by the affected, people should loose interest in their channel and it would die off because there’s no profit when nobody watches or trusts them.
On another hand, there are some trustable ones but of course who those are varies from person to person, for now let’s just wait until the ones that cant survive without the government’s money die off and we’ll put up to public scrutiny the rest
