The functionality of the App and the policies and choices of the business are intrinsically tied. In this case their choice directly affected the functionality of the App: I was unable to buy or even view certain stocks. In my opinion that is, without a doubt, App functionality that should be subject to user review and rating.

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.
