The absurdity is more that even if you watch a channel broadcast on YouTube you still need to pay. Even if the channel is from some other country, you pay to fund the BBC (which is biased against that country in its reports no less)
I doubt you were referring to CNA specifically, just picking an example of live TV on YouTube.

So I imagine most Youtube/Twitch indie content wouldn’t count, but any foreign TV broadcast would. It’s ridiculous.
