Yes, agreed, it definitely needs moderation. But I don’t think it needs singling out (again, not saying don’t moderate).
The bigger picture is a proliferation of online extremist speech in general. And yes, Google may have done well to moderate play store reviews (anecdotally), but they certainly haven’t done well with YouTube.
But I would suggest that focusing on any one online forum / store / outlet / etc. will naturally miss an important trend, and the reasons for that trend should be understood – while concurrently doing everything possible to limit this kind of hate online.
Oh no, please, don’t
