Hahaha you must be from one of the 2 countries with YouTube red.
(I know it's probably not literally 2 countries, but it's available in very few countries.)

Googling around a bit, it seems that Google's attempt to include everything under the sun into your YouTube Red subscription is to blame...
They could just give you ad-free youtube. But instead, they want YTR to include their YTR-only premium content, and also they want to throw in Google Music... all of that requires decyphering copyright laws and potentially registering as a royalties collector (IANAL). Typical Google behavior, an inflexible all-or-nothing approach.
