Let me repeat that: it's an email client. People's days were ruined by this news? Google is stupid and evil and-I-don't-know-what-else because they acquired Sparrow? The developers of Sparrow are evil because they didn't do what you unreasonably expected them to do? You people need a serious reality check if these were your thoughts. Heck, the app didn't even stop working.
Now, with all that being said, I can understand a little frustration about knowing for certain that your apparently-favorite app will not be updated anymore. Fine. I get it. But can we cut out approximately 90% of the fury?
