While I think Facebooks complaints are stupid. The statistics/data they collected is interesting and does paint an interesting, and potentially anti-trust picture. (if we go by the same standards that the world used to back when Microsoft was being sued).
with first party apps clearly being the most dominant apps on each platform (and there's valid reasons for that case), it does show that for competition to Apple's apps, it's an uphil battle, where apple (and even google) have a competitive advantage at the Application level and monetization of those.
As an example of what the data points to:
Lets say you're trying to start up a new music streaming service. not only are you competing directly against Apple's pre-installed first party App, but you're also automatically at a financial disadvantage due to 30%/15% payment processor requirement. A new upstart might need to charge 12.99 or more for break even, or profitability, while Apple's pre-isntalled first party app they directly advertise and recommend only costs 9.99, with 100% of the proceeds going to Apple.
this is the point th at a lot of the posers in the first page seem to conveniently ignore so they can make some lame comment attacking facebook. Facebook is a bad company, but the data here (if accurate) does paint a troubling picture that both Apple and Google have essentially taken a near monopoly by having their first party service applications pre-bundled and top hits on their respective stores. whther you want to admit it or not, that IS anti-competitive behaviour and historically had regularly been called anti-trust business practices. in the 90's, Microsoft was forced to remove IE from Windows over similar practices and allow users to chose their default installed browser. Eventually once Apple/Google political stranglehold starts turning against them, I wouldn't be surprised to see a few nations, or the EU absolutely hammer these companies for Anti-Trust
