The BBC is under threat because they refuse to innovate. They're not yet doing full scale 4k streaming, programs disappear after X number of days, and to be quite honest, they don't offer the value for money Netflix does.

And BBC's own shows, like Planet Earth 2 are already on Netflix, so why would you even still need a license fee at that point?

It made sense 20 years ago when there were only 5 or so channels, now there is so much content available so quickly (even if it's not "legal") that people are realizing it's a waste of money.

Which is true.
