> Open source is a no-strings-attached gift, and all participants should recognize it as such.

I've always felt this is incorrect. First, because lots of people use open source to further their careers, it isn't. Open source contributions are paid work if you benefit from them in any way. Second, if you use open source yourself, your work is no longer a gift. You're contributing back to the community you've taken from. The person you're being a jerk to because it's a "gift" might be the author of other software you've used.
