I'm still in favor of permissive: 1. Not all copyleft licenses are compatible between them. So, you may be able to use A||B but not A&&B. 2. Downstream from #1, you end up seeking legal assistance in order to build the thing you want to build and understand what is the proper license you have to use for the result using A&&B. 3. Permissive made much more sense when we actually distributed software. When it's all about services, it doesn't matter, does it?
