Is it lazy? Well, maybe.
A lot of these "celebrities" aren't professional video editors. Some go more all out than others (Angry Joe's reviews... he does costumes and skits for), while others go a more minimalist route (Jimquisition is generally just gameplay footage mixed with still images - stuff you can do with windows movie maker). However, does that make the editing "easy"?
I do some video stuff on YT for Zelda Informer. I use Sony Vegas pro 13. I am far from a professional video editor. To even edit an episode of "The Boss Man", it takes me nearly a dozen hours for 10 to 20 minutes of footage. If you watch an episode - outside of a green screen effect you'd assume I haven't done much else - but most fail to realize that the more amateur you are with video editing, the more work it takes to actually get an episode up to an acceptable level of quality.
So, let's dive into Jump cuts. There is a natural assumption everything is done in one take and spliced together - and yes, most videos are are single files split up and put together. However, sometimes that single video file took a half dozen takes to get right. Sometimes you fail to launch, other times you lose your train of thought, and even if you're reading a script, you'll catch yourself sounding like you're reading a script instead of feeling more natural.
All of this causes take after take, until you finally get one take that has everything in it the way you want it to be, even if you have to cut out some stuff due to a cough, some background noise, or because you were being a bit too repetitive. As others said - to keep up the consistent quality and pacing, jump cuts are an obvious play for amateurs and have been as such since youtube came into existence. Heck, even if you used a few takes and put them together, jump cuts will be there.
In the example given, outside of the first jumpcut - it at least makes some logical sense. He jump cuts each topic - so the topic itself gets the best attention to editing it can. He also focuses the camera on him than zooms out so he can put some video/imagery on the top left like a news channel. The only way that can happen naturally without a jump cut is for someone to be on the other end of that camera.
Generally, YouTube celebrities are doing all of this work themselves. Meaning they are using a stationary camera - so if he wants to create that effect, he has to readjust the camera for those portions. The easiest way to transition is a jump cut, and those are widely accepted in the YT community.
There is a lot of effort that goes into editing even the smallest thing for amateurs. I feel it's important we understand and appreciate the amount of work that goes in and that while jump cuts may not be to someone's personal taste, it's widely accepted in the community they hail from and if they did some sort of "fade in, fade out" effect, it would actually screw up the pacing. It's on of those "necessary" evils, especially for what boogie is trying to do with this video.
