The LTT video was painful to watch. I don’t know much about USB or USB-PD, but it was clear they didn’t either. It felt like they were just rambling with some vaguely technical jargon, with no actual understanding.

It seemed more like the technical guy wrote the post and 'they' made it into a video format without really explaining it.

I think they did a bad job. They struck a poor balance between not explaining it and trying to explain it. They should have gone full technical or not at all and stayed very high level regarding the issue of bespoke protocols.
