I think you are referring to the Youtube gurus teaching stuff.

Its actually 2 fold, the short term goal of raking up some youtube views and getting the youtube ad money. Second is to pad the CV as an "advanced developer with lots of knowledge to share", it helps to put on CV and also be considered for some training positions which is demand as many are rushing to get into tech where "even kids are minting money".

I know a guy that put up some coding videos on youtube to be a "youtuber" and one of the big tech firms in India hired him to train their new recruits.
