Charging your customers, promising features, and then selling your business and going back on those promises is not good business. It's usually great to see startups get bought and winning but in this case they had a profitable business and they screwed their customers. Not to mention the half price sale they had days before the acquisition. If they knew the acquisition was happening this week and they did that sale to have a few big days before shutting down it was a really scummy move.

>> "Software is a business"

It is, but selling an app for 18 months and then selling your company is not. It seems to be ingrained in tech culture that you should sell your business. Why are so few companies aiming to become profitable and build a sustainable business? I understand companies like Instagram with no revenue stream selling, but Sparrow had a solid revenue stream.
