It comes from YouTube wanting to compete with TikTok, yes. And it's become so ridiculously common on YouTube because the platform pushes the hell out of shorts compared to normal videos; as a creator, I can get 10/100/1000 times more views from a short than a normal video covering the same topic. So a lot of creators ended up jumping on the shorts train as a gold rush.
Of course, it's probably not great in the long term since shorts viewers and longform content viewers are not the same and your CTR can be destroyed thanks to shorts subs not watching your longer videos, but the easy views and subs are still enticing nonetheless.
