Parler wasn’t pulled from Google’s app store for discussion of Conservative policy. It was pull for hate speech, incitement, and for the illegal conspiracies being plotted. Plus Parler isn’t enforcing their own terms of service.
If it was just politics then Google would also pull New Republic magazine.
Apple has said that they need to step up their moderation game and they can get back into the App Store. I’m guessing that would be good enough for Google as well.
Keep trying.
