recommends an interview with John De Goes in which he argues: "The tools market is dead. Open source killed it
." The software developer turned president of N-BRAIN
explains the effect that open source has had on the developer tools market, and how this forced the company to release the personal edition of UNA
free of charge. According to De Goes, selling a source-code editor, even a very good one, is all but impossible in the post-open source era, especially given that, "Some developers would rather quit their job than be forced to use a new editor or IDE." N-BRAIN's decision is but one in a string of similar announcements
from tools companies announcing the free release of their previously commercial development tools.
