I might be missing the point, but I’m not getting this glorification of stupid acts.

It is annoying to see idiots get a lot of attention, but really, it is not a glorification of a stupid act, it is just a video of one. Furthermore, it would live on in all of those videos that point out just how stupid it was, unless Youtube also removes those - but they are informative, I would say.

I'm generally in favor of idiots that do illegal things then posting video evidence of them online. I don't think it glorifies the act if YouTube then demonetized the video with a note & link back to the FAA's ruling. Showing stupid things & their consequences seems reasonable.

Would you feel the same if this became the top watched video for weeks, with a lively comment section mostly leaning towards "omg that is so cool! I want to top this!!!"?

I wouldn't - which is why I don't mind if it's taken down.

I'm hesitant to advocate taking something down. I'm not saying it should never happen, but this doesn't cross the threshold for me. In this instance the video creator wasn't encouraging people to do this and the audience response wasn't to jump in and do the same thing. Also videos that would fit this category-- filmed evidence of illegal activity & subsequent consequences (which I think Google should add to the video)-- are not likely to become popular in the thought experiment you describe. If they did, maybe I'd revisit my opinion.

On the other hand, if content is encouraging people to do harmful or dangerous things then that becomes a different issue. I'm less uncomfortable with YouTube trying to stop Tide Pod Challenge videos which were basically encouraging such activity: The first two weeks of 2018 saw about as many poisoning reports from this as most entire years before then.

What glorification? This is a thing that happened, and it's incredibly newsworthy. Prevent him from profiting off the video and leave it up. There is no reason to do anything further from YouTube's perspective.

How is "treat this video like any other video" (i.e. do nothing) a "glorification"? There are tons of videos of incredibly stupid and dangerous acts on YouTube.

The existence of something is not glorifying it.
