If Apple truly insists that they know better than the publishers, why not have an option for "Apple's font choice" vs "Standards" in the app? If they still want to impose their font choice on users, they could even have it enabled by default. This is ridiculous that they can just ignore standards, and people will write it off because it's Apple. Design matters, but so do standards. Don't impose design over standards. If you must put design first, don't completely ignore standards like Apple did.
