I understand that right now, it's some tiny app that doesn't affect too many people, which is fine. But imagine if tomorrow, Stripe or Balanced decided to stop certain conservative organizations from using their app. That would definitely be considered a suppression of personal expression and (imho) cause quite a backlash. As your organization grows, you have to be more and more careful about separating your personal and political views from those of your customers. I am glad that this company is not building anything that might be considered essential to startup infrastructure.
[Edit: To clarify a bit more, I'm trying to say that pulling an app from a store / suspending a service for reasons of personal disagreement is a disservice to the users of said app/service. Showcasing Brendan's role in donating against Prop 8 is perfectly fine.]
