Here are several comments from last time this was posted that completely dispute the characterization this article makes:

https://news.ycombinator.com/item?id=32259325 (lead designer of Unity)

https://news.ycombinator.com/item?id=32259074 (lead of Ubuntu Desktop product)

https://news.ycombinator.com/item?id=32258650

https://news.ycombinator.com/item?id=32258035 (founder of GNOME)

This article really shouldn't be allowed to be posted to Hacker News anymore. Anything with this many errors, and is essentially a mickey mouse investigation, isn't worth discussing again.
