This is probably what made me double-take the most.
I don't understand why Guardian were denied permission to use the code. Sure, OWS aren't under any obligation to, but it doesn't really feel like it's in the spirit of openness at all.
The code might be 'open source', but it's neither free as in user freedom or beer, unless you're giving Facebook or Google your metadata now.
If the code can't be reused, it's pretty hard for users to move to something else. Unless that something else is totally starting over again from scratch.
It just feels weird that because of the Apple situation, in this case the GPL appears to work directly against user freedom.
I think a lot of people have been taken by surprise by that, to discover the platform is not what they thought it was.
