Technical documentation of API, Language constructs, and usage (a la mandoc) should always have a standard-compliant (any widely accepted help manual format like mdbook or texi) text form licensed under the GNU Free Documentation License (FDL). This is to ensure that freedom 01 (“The freedom to study how the program works”) is not obstructed in any way.
Videos are tougher due to having a much wider arrange of factors. First off, you’d want to make your videos accessible (using subtitles, on-screen graphics and not just a narration all the way through, translation to other languages). You’d also want to be able to share that video among your peers without obstruction. Just having it be hosted to a proprietary mass-media site like YouTube will not be enough. I have doubts about the “hit record and magic happens” premise, videos are a lot more daunting than text formats if you don’t have the prerequisite equipment and skills beforehand.
If you really want to create videos, you should have a text alternative to the video or at least a technical summary of the video’s topics attached alongside the video so that you can leverage both text and video alongside each other.
Yeah these chumps are total tools that’ll just boost piracy even more. How do you fail this hard at talking to kids? If you tell a teen to “postpone needs,” you don’t deserve to be around teens.
