What the fuck is everyone's obsession with publishing their personal website or blog under a license? CC-BY-whatever. Nobody cares, why even use a permissive licence, do you want your personal information and writing stolen?
I only partly get it for software, mostly the software that's of critical importance to free communication and free use of the hardware that allows communication.
I do think open sourcing software is the way to go, to gain trust from your users. Personally I would publish all of my software under All Rights Reserved, I do not allow anyone to use this software without my explicit written permission. If a company wants to use it they can pay me. I like the AGPL for that reason too. If you're a one man shop using it for your single income I'll grant you a waiver, but if you're a large company, screw you, pay me.
I think the people that see FOSS as a purely ideological movement are wrong. I think the majority of it is just big companies crowdsourcing their software development, debugging, testing and bug fixing.
Every time I encounter a bug in something someone else wrote and have to fix it myself or write a bug report, I think I just got used for free work by some company that's gonna use this fix to make shitloads of money and not give me any of it. Especially after the whole FOSS movement got EEE'd by Jewgle and Microjeet.
