In the US, it seems that courts do not care about “on Apple devices”. They see two markets: mobile devices, and laptops/desktops. Blink based browsers make up a minority in the US on mobile devices due to the dominance of Apple, and while they do have the majority on desktops/laptops, Safari is still double digits and Firefox has a small slice of the pie as well. Even if that was enough, there would still need to be evidence that this is due to anti-competitive measures and not true user preference. This will be hard because Microsoft isn’t publicly being compensated for choosing Blink for edge, nor does google have any wide-scale measures to coerce users onto chrome other than marketing in their own products and services.
