So basically Veritasium is selling ads to keep making more videos and sometimes he makes things simple enough that high schoolers can understand it? Ok :)
I mean, if you want to consider "selling ads" to include selling undisclosed ads as organic, original, and good-faith reporting of accurate information, then yeah, sure? I sure wouldn't, though.
Sure. Here's a video critiquing one of Veritasium's videos I had issues with. Check this[1] thread for further details about it from me and some good rebuttals from another commenter.
