USB-C is an absolute shit-show. Half a dozen types of identical looking cables all with different performance and compatability. They can be power only, USB-2 only, USB 3, 3.1, 5gb, 10gb. Some can carry 5A, others only 3A. Some may support thunderbolt. Cable sellers and manufacturers can/will claim anything.

For people selling USB-C devices it’s a massive support problem. It looks like the device is defective, but someone may just have swapped out the cable for their phone charger cable and there’s no way of telling.

I wonder what made youTube decide to fix this loophole? These days the vast majority of people use phone apps or smart TVs to watch. The number of people using Firefox plus ad blockers must be quite small and it’ll be a constant effort to keep updating their anti ad block algorithms.
