How much of this is down to the editors and producers knowing only the MTV, quick-cut style of video production (which seems to have been en vogue since the '00s) and not having any mentorship or guidance from the old guard? If that style of video production is all you know, then everything is going to have that same quick-cut style of production. Similar to web developers who only know JS...every problem becomes a JS problem to be solved in the JS way. (e.g. if all you have is a hammer...)
