My standard is consistent. Apple and Google control their respective OSes. They are not general purpose OSes and there's nothing wrong with locking down the software users can run. Having a store and charging a commission is also fine, however it makes sense that all developers should be on equal footing with respect to the store and their app size(in terms of download) i.e. no sweetheart deals.

I do think there's a strong argument to be made about forcing Apple and Google to facilitate the ability to install a different OS if the user wishes.
