Apple is going to (mostly) obey the letter of the law but they will continue to resist strongly in every way they can. Onerous requirements, arbitrary restrictions, overzealous enforcement, and most of all bad APIs with limited capabilities and no workarounds for bugs.

Shipping a good and complete browser engine on iOS will require more than just developers. You'll also need a team of lawyers to threaten and sue Apple to get their policy restrictions relaxed and APIs fixed.

I doubt Mozilla or Google will be willing to spend the many developer-years and lawyer-years it will take to fully port every feature of a whole engine and properly maintain it in such a hostile environment, just for the Japan market. I expect to see some hobbyist-level ports but not something worth using for a long time. Unless other countries follow suit.

Probably not, at least not from Mozilla themselves. They cite onerous requirements and the difficulty of having to maintain different apps for different regions.

There is ublock origin lite for Safari in the meantime:

(it's great)

Probably not, as the same rules were applied to Apple devices in EU earlier, and no third party browser engines appeared.

But right now you can use uBlock origin lite in Safari. Or any other of multitude of other adblockers.

FYI. iOS Safari already supports uBlock Origin Lite. iOS Firefox can do the same anytime but it already has some tracking and content blocking built in too.

Could’ve happened some time ago already in the EU, so there must be reasons for Firefox an Google not to ship their own engines (yet?).

uBO lite works pretty well on ios/safari for me.

You can actually use full uBlock origin in Kagi's Orion iOS browser.

Nope. Apple has successfully made the rules so complicated that we still don't have any 3rd party browser engines in the EU, more than a year later.
