Between Apple's alteration to their AppStore T&Cs and Twitter's change in API usage T&Cs, I think we're facing a little bit of a correction in the "internet is free (as in freedom)" movement. This is a natural consequence of a model where corporations roll out features before they've figured out how they'll monetize them. In other words, if I'm not sure how I'll make money from my service, I must reserve the right to change the rules to support a viable business model at some point.
Personally, I hope the backlash doesn't push things too far in a conservative direction, but I do think companies should put a little more thought in to the future of their product's interaction with the target network of developers and affiliates before they open the doors to integrate.
