You still aren't referencing a law. You are just saying you don't like it.
I ANAL and am not a lawyer but: There ARE laws about saying if a video contains paid advertisement. That is why basically every single video on youtube has the "contains sponsored content" tag.
There is no law saying that the specific seconds of the video need to be tagged. Which makes sense. It has been a minute since I watched network TV but I don't recall giant "AD" on my screen any time Hikaru Shida wasn't.
