It's one thing for the company to make choices that people disagree with but don't affect the actual functionality of the App. This could be environmental policies, partnering with a controversial government, using tax loopholes, etc. People going on brigades to review bomb an App for these types of issues are what should be protected against. Mass shifts in public opinion due to actual changes in how the App behaves should not be protected against.
1. That's not how people treat reviews (people will leave a positive review if they love the business but the app is crap), so it's misleading to only enforce such an ideal here, with negative reviews.
2. In this case, the business effectively is the app, at least from the user's perspective. The app wouldn't let me even look at GME/AMC today, much less buy it. That's not what I want from a stock trading app, because it's an annoying experience that leaves a sour taste in my mouth, so 1-star it is.
