I don't see how they're "selling" anything. Web Integrity requires no money to change hands. If implemented, Netflix + Spotify would owe Google nothing.

DRM is the tool that guarantees money will change hands. Without it, there is nothing but a social (legal) threat to prevent people copying and distributing copyrighted content for free.
Forcing users to run the DRM-infected version of an app creates an incentive for Netflix and Spotify to participate on the Android platform; which in turn strengthens Android's position, and the Google Play Store as a market.
This incentive goes both ways for YouTube, because it is owned by Alphabet.

Yes, but that's not the point. Google wants Netflix and Spotify to have Android apps. Netflix and Spotify want DRM infecting their apps. Without this system in place, users can disinfect the Spotify app, and listen to music without paying Spotify money (or watching ads to pay them indirectly).
Without providing the environment for functional DRM, Netflix and Spotify can simply refuse to make Android apps. That would be a pretty weak threat, except that YouTube wants the same thing; and that incentivizes Android to play ball.
