Of course I would love to see Gecko running on iOS. I just don't like the possibility of Google's browser dominance become even stronger either. It's a hard one.
I understand your frustration that you can't use the browser you want on the devices you want. That is annoying. However, *now* is the wrong time to go after Apple. Get more people using other browsers on other platforms first.
Wikipedia suggests this breakdown:
> As of November 2022, Android, an operating system using the Linux kernel, is the world's most-used operating system when judged by web use. It has 42% of the global market, followed by Windows with 30%, Apple iOS with 18%, macOS with 6%, then (desktop) Linux at 1.0% also using the Linux kernel.[1][2] These numbers do not include embedded devices or game consoles.
(from https://en.wikipedia.org/wiki/Usage_share_of_operating_syste... )
Android and Windows make up 4x the number of iOS users on the web. When the % of Chrome users on those platforms goes down, and Firefox and others go up, to a level where any of them could temporarily steer the direction the HTML/W3C standards take, _that's_ the time to go after Apple. Until then, lean on the fence Apple are holding up for you (and getting Google to pay for).
