I cannot help you with your contempt for other’s choices and your general cognitive dissonance. However do consider:

- Creators use YT for ease of hosting, earnings for their effort, widespread dissemination

- Users choose YT for ease of watching, content discovery, non-bloated UI/UX

Google uses Ads to cover significant hosting and bandwidth costs, as well as to build quality features to help both creators and users alike.

If this logic doesn’t make sense to you, so be it. But your tirade is both entitled and ignorant.
