Google already does this to a certain extent by allowing other app stores and will I think very likely move towards certifying other payment frameworks as app store payments is not a significant revenue stream for them - they'll probably negotiate this as part of an antitrust deal with prosecutors Apple OTOH seems to depend on this for 15-20% of annual revenue and this is going to be much more difficult for them
