I don't understand why are you being downvoted, as GPL does actually impose some restrictions in comparison to BSD/MIT. These restrictions may be for copyleft, for benefit of end users, pro bono, for whatever else, but there are restrictions, and the term "restrictive open source" captures the essense of this license. Also, these restrictions won't disappear no matter how low your (or mine) comment is downvoted here on HN.
