I think its more "It is legal for me to ban coupons at my store" and then suing another company for not letting you use coupons at their store. I'm not 100% sure though
Has Apple sued Google for this, though? I haven’t heard of any lawsuits over this between the companies.
I think in this case, the hypothetical lawsuits would be between companies that make iOS apps and Apple. The companies that make iOS apps want to have their own payment system where Apple doesn't take a cut.
Right, but Apple could just say Google has different policies... they never argued that google legally had to allow them to accept outside payments. They would just say "Google could have prevented us by policy legally, but didn't want to."
Isnt it more like I am banning all my customers to use coupons on my platform. Then circumventing this ban and using coupons on another platform anyways.
