A carpenter that has made a chair don't usually go and enforce some legal contract in how the chair may be used, modified, sold, and do that for 95+ years after the carpenter has died.

The morality stance has nothing to do with the act of building or creating. I have always said, agree to sign a contract where you give up the ability to enforce the proprietary license and I have no issue with it. The problem is that no one would use a proprietary license unless they could enforce it, and thus the morality issue of a proprietary license lies in how the license get enforced in the legal system. This is not the first time a morality issue has been raised when people get put in jail because they helped someone in need.
