I don't remember being required to use a 7-11 credit card at a 7-11 for every transaction but nice try.
And, in stark contrast to the MS antitrust case, Apple doesn't have 97% of the market share.
That said, do you remember having to use Disney money in Disneyland for every transaction?
I remember it being a fun option to use either Disney or US dollars in the park, maybe it was required at some point, but I don't remember that.
