Courts also decided you couldn't bundle a web browser and then turned a blind eye when it's done on a different platform with draconian restrictions against even installing an alternate browser.

They didn't "turn[] a blind eye" as they weren't asked the question again. There was no legal precedent established by the Microsoft case that required all future operating systems to have a replaceable browser engine. Also, the factual situations were quite different: Microsoft had a de facto monopoly on PC OSes in the late 1990s, while Apple never had a monopoly on mobile devices.
