I don't see how caycep's comment enhances my understanding of the released software. It's just a big dump of ad hominem (as are practically all the other comments).
Palantir open sourcing their software could and should be viewed through a PR lens, an action meant to build favorable reputation in the developer community. Maybe caycep could have elaborated on this more, but I understand the point: Palantir has a mixed history, so we should take the positive with a grain of salt and beware.
