Most moderators overwhelmingly rely on the utility function you get in 3rd party apps that isn't currently in the official app, so I genuinely believe this is one aspect of the protest. I could be wrong, but I genuinely can't see a situation where this amount of action is purely around seeing ads.
Pretty unanimously, 3rd party app developers have said they'd happily show Reddit's ads in their feed, but Reddit never came out with this feature. I don't think any 3rd party app developer was expecting a free ride on Reddit's API forever.
