I think this is setting a dangerous precedence.
Google in particular has been very "active," not to forget also: https://www.businessinsider.com/youtube-will-ban-anything-ag... ("video that 'goes against' WHO guidance on the pandemic will be blocked")
It's not a political stance, it's a moderation action.
Google, Facebook, etc. are just bad moderators of their platforms.
Selective enforcement of moderations policies is bad moderation. Implementing automated moderation without proper quality control is bad moderation. Implementing automated moderation without proper appeal processes is bad moderation.
The moderation policy is insane, but I think how moderation is done is even more insane.
For the record: as a paying Podcast Addict user, I think this is a shitty action by Google. I just don't see how it is unconstitutional.
NB. I hope something good comes out of this, like more people discovering and using third party app stores, or being able to run apps on android auto even if google hasn't approved such apps (hello TomTom).
Given that there is selective attention given to different political subjects it is by definition a political stance.
