You're almost certainly right. I hate searching for info on something that could be easily explained in a paragraph and maybe a screenshot and instead I have to watch through some video--usually with an ad. I confess that I really resist making videos of things unless I have no choice but I know a lot of people prefer them.

A well-written and illustrated explanation like this one? I can't imagine preferring a video unless someone just wants some background noise and they don't really care about understanding the subject.
