Just sent the following e-mail to them: I just recently purchased Sparrow for iPhone a few days ago, regardless of the lack of push, since I knew I'd be supporting a small team with developing an awesome app. I was particularly excited for the promise of push notifications coming in the future (I was going to be more than happy to pay for a subscription service). So now that this Google acquisition has occurred, you've said that you are no longer going to be working on features for Sparrow. Does this include previously promised features, such as push? If so, it seems like you've slapped me in the face with a huge middle finger. I paid for both of your applications in hopes of a future of growth for what was already an awesome e-mail client, and now you're telling me that you're killing development? That's a really shitty way to treat your customers if you ask me.
