Now we know why!

I suspect you have the causality on this backwards: https://news.ycombinator.com/item?id=38579175

Wow, I read that thread with great interest at the time, and reading it now knowing about the acquisition is quite the mind blowing experience.

I worked at a startup that got acquired by a big company and we switched our custom proprietary license back to Apache 2 after acquisition. The reason we switched in the first place was because it's what we thought was best when we were out on our own. Being owned by a hardware company, you can have the software for free. (We still sell licenses and have a cute little license key validator, though.)
