content: Well, they HAVE to make money, somewhere. Creating a long video, editing it (sound, lighting, and cutting), and exporting/uploading it takes A LOT of time. Not to mention you need some decent computer hardware to edit and export a high quality/resolution video... I'm talking about gaming-rig quality, in order to work with any kind of limited time frame.  And Google's AdSense doesn't pay out a lot, especially if users use an ad blocker, or skip the ads. It's actually so little, I don't monetize my videos. It's not worth annoying the few people that watch me with ads.  I have a job, school, and other things to do, beyond making and editing videos. And food isn't free.
