pretty simple. [the video site] sees how popular tiktok is and wants to get a slice of that “short format” pie. It incentivizes content creators to make content that fits the format by promoting it on the algorithm. If there is a shortage of content in that format (and for that type of audience), anything semi-decent will do, eg. highlights from longer videos. As the algorithm needs to fill that quota of videos somehow
yeah that’s not good, may get you prosecuted under “material support” laws
