I'm having a bit of trouble reading your response, it seems like you're driving at a few points simultaneously. (You only quoted one word out of my reply so I'm not sure exactly what you're trying to argue.)
Are you defending AGPL and saying that proprietary SaaS software shouldn't use GPL code? Then I think you and I are 100% in agreement.
My post was in response to the grandparent who seemed to be saying that the GPL is A-OK to use in proprietary web services because it's only relevant "when you want a licence to redistribute that software (or your derivative version)". I was explaining that that's more of a loophole in the GPL than it is "not relevant".
I'm not basing a business on limiting others' freedom, I just want to write a dumb rails app for adding users to LDAP, or any other myriad of dumb reasons you'd want to make a dumb internal service. And I basically can't touch the GPL unless I can also convince our legal department to let me GPL the dumb tool and distribute the source code. Since things we distribute have a bit of brand identity to them, it would make my company look bad if the tool sucks, or it's not general-purpose enough to be useful outside my company, etc. So it's just not worth the hassle to go through all that for some dumb internal LDAP tool.
So instead I stick with MIT/apache/etc permissively-licensed libraries in my dumb internal tools, find bugs in those libraries, and submit fixes upstream. Ironically this is the exact same thing that GPL proponents say would never happen if everyone used permissive licenses.
I don't want to GPL my code and distribute it because I don't want anybody to see how bad it is, not because it's some "secret sauce" for my company. It's just a bunch of glue on existing libraries anyway (basically a variety of ruby gems.) The GPL is far too difficult for me to use in this case, so as a result I just don't touch it.
