At least when you deal with Apple they don't dress it up, they make it abundantly clear that they'll shaft you if you try and step around the rules, Google danced around it with the rally cry of 'open!' a lot more.
Google was fine for some time, but their recent (last 2-3 years?) actions and policy have left me completely stunned. Maybe has to do with the influence they have on the Web but it's infuriating to see a self-proclaimed innovation giant to make efforts in drowning the business.
Android does allow alternate app markets to be installed or applications to be installed directly. You would never get the reach of the PlayStore, but still this would offer a way around this.
