Yep. It was only recently I properly understood why I was always reluctant to contribute to a permissive #FOSS project. I knew it was bad, but Redis have given the example I needed to explain it in one word.
All my own projects are GPL and I will never contribute to anything like #MIT, #Apache or #BSD licensed code. If I need a project I'll just fork and switch it to GPL. #Licensing
