If the deal lasts for more than 2 years, then he has made a serious error.

Annoying to both pay for spotify and get hammered with ads. Granted I pay for the music, but it's still annoying as all.
Since I still have to listen to ads, i'm thinking of just dropping the subscription and hoping there becomes a method to break this Widevine trash. I encounter a bug with their app on a daily basis and I am tired of it. From what I gather, there are different levels of Widevine encryption that limit video quality but the lower levels are crackable. I hope someone smarter than me tries the crack on the JRE podcast.
On Spotify not only he got some cash upfront, but also significantly mitigated this risk, since platform is way more aligned (i.e. it's important business for Spotify and a footnote for YouTube).
