I knew Gosling when he resided in Calgary. A very bright guy but he was also extremely possessive of Java. Even during the Sun days it was clear it was his baby, and nobody else’s.
I can imagine him being very frustrated at oracle and google where motivations are different enough to not cause his ego to be fed.
And as much of a scourge Oracle is they have moved java forward much fast and further versus Sun. All with gosling being sidelined. Perhaps that is part of his motivation for this article. Someone raised his baby better than he could.
