Most slow motion videos on youtube has a section on the setup, the backyard of the producer, the equipment etc. Just give me a slow motion video without all the interruptions.
Funny, that’s exactly what he does in this video https://youtu.be/Cnn9CfsYJqc
At 1:35 he shows his backyard here https://youtu.be/1Wnd6c42w7w
The setup is meaningful to people who want to know how it was filmed. If you don't care for it you can always skip it. Why ask for the video to have less content that other people might want to watch just because you don't?
I kinda like TikTok because you can often find short, no-nonsense videos like this, that you can’t find on YouTube.
Ads are content with an ulterior purpose of, well, advertising.
And the suggestion to skip is precisely the opposite of "just watch whatever's on TV", it's more of "if you don't like that channel, why don't you switch to another one?"

Regardless, the argument is not whether or not one should watch the behind-the-scenes content, it's the existence of the content in the first place. If the behind-the-scenes is there, you can skip it if you want, but if it is not, then the one who wants to know how it was filmed will be left with no options.
Of course it doesn't mean it has to all be on the same video, but the nature of social video platforms ends up requiring that, otherwise the BTS is monetarily inefficient (if the channel in question is in it for the money).
