Psychology of Non-Collaboration

These may be traps that people fall into, so they are worth noticing

1. "Nobody in my area is he not Linux, therefore it must not work."
2. Use of exclusive tools - "I want to use expensive AutoCAD, because it gives me exclusiveness. Few people can afford it, thus it's a marketable skill (by exclusion)"
3. Or: "If everybody has it, I'm not special" - grading FreeCAD.
