Why would the BBC be allowed to collect money on services it does not provide? This is basically saying “everyone must pay this fee, or unplug their internet”.

I think that it’s because the BBC puts content on YouTube (and I assume either doesn’t have ads enabled or wants more money than they generate).

I guess I could understand someone saying "well, with TV, I have to watch British brosdcast stations, and with YouTube, I don’t, but I’d think that the same would apply to TVs using satellite receivers, and I assume—though I don’t know, don’t live in the UK—that satellite TV users are also subject to the license fee.
