The title is pure clickbait.

Linus rants a little about Youtube serving 90-second unskippable ads, but then swiftly moves on to other topics, because ultimately LTT’s entire business model relies on advertisement revenues from Youtube.

I will point out something Linus won’t tell you of course, since he has a vested interest in not telling you: you can watch Youtube without ads using ad blockers, or one of the many third party Youtube players such as FreeTube, Newpipe or Grayjay.
