This 30% cut is being contested right now and over in the US, a bipartisan group of US senators have introduced legislation that could ultimately force Apple and Google to give up some control over their app stores.
The legislation is penned by Senators Richard Blumenthal of Connecticut and Marsha Blackburn of Tennessee, and is also co-sponsored by Amy Klobuchar, who is the chair of the Senate antitrust subcommittee.
One of the provisions of the legislation is a clause that would effectively prevent app store marketplace owners, like Apple and Google, from forcing developers to use a payment system that they own. If this sounds familiar, it is because it is similar legislation that was introduced in South Korea about a week ago.
Of course, whether or not this will be passed into law remains to be seen, but there is no doubt that there is a mounting pressure on companies like Apple and Google to ultimately reduce the cut that they get and to give developers more control.
