Honestly it's just amateurish editing combined with single-camera footage. Lot of modern TV shows and movies also cut every 1-2 seconds, and reality/contest TV is worse than YouTube with cut frequency. But, they do things like overlapping the audio through the cut, switching camera angles on the same, "continuous" scene of events, using good cinematography to make the cuts feel natural, like you're just turning your head as someone else starts speaking, or to respond to some new event happening "over there." The criticism of simply the frequency of cuts seems weak to me, it's been like that forever with most types of video entertainment content.
