Yes, and is also very IE like in that it's not evergreen, various iOS devices stuck on specific revisions that Apple has left in various states of broken.

i have an iphone with safari, firefox, firefox focus and chrome, ...

iPhones aren't allowed to have web browsers that aren't running Safari on the back end. They can have different names, different UIs, but at the end of the day it's the same browser.

I don't know why non iOS browser play the stupid pseudo support game with Apple, it just makes it confusing for users like the parent comment... playing into Apple's hand, helping them pretend that it's actually a fair ecosystem with choices.

That's easy. Users want their bookmarks, history, passwords, etc synced across devices, and so if there's no Chrome, Firefox, Edge etc for iOS to accomplish that on iPhone/iPad, people who have multiple Apple devices would likely switch to Safari and those users would be lost. Additionally, in the case of Google and Microsoft, they'd be opting out of those sweet, sweet streams of user data if they had no iOS presence. And so, those browsers exist, just built around WebKit instead of Blink/Gecko.

Apple does this for a few reasons:

1) to prevent web apps from gaining a foothold. Modern web standards aim to provide native-like utility, performance, look, and feel. Apple purposefully holds their device back so companies are compelled to deploy native apps.

2) to prevent Google from taking over their platform. Chrome could give Safari a run for its money and "steal" user attention away from Apple's key platform pieces, providing a foothold for Google on iOS.

Firefox is the browser I want to see be the competition.

Extremely unlikely unfortunately unless the planets align and Google ceases all promotion of Chrome and Mozilla dramatically improves their own promotion game. Firefox would probably need more tangible reasons for people to switch too, because realistically the masses aren't going to care about the privacy or marketshare angles.

I don't see how Mozilla could "improve their promotion game" to stand up to that.

But that alone wouldn't suffice. From what I've seen of Mozilla's efforts to promote Firefox, they don't have any idea of how to appeal to the broader audience, or really any audience beyond the privacy-conscious. That Firefox allows better control of one's data is great but it's not nearly enough to carry most people past the friction point of switching browsers. For that you need things like major advantages in battery life and features that fix common web browsing annoyances.
