It's an embarrassment that the leading video platform, belonging to a multi-billion-dollar company, has a worse user experience than a simple video file with only the web browser's built-in UI controls.

You're surprised because you view Youtube as a video platform. It was that once but now it's an advertising platform that happens to show videos.

Luckily for now you can pay for YT premium. It makes the experience so much better. no checking for ads every-time you skip.
