Firefox on Android supports ublock, not sure why it wouldn't support it on iOS

It's because Apple does not allow Firefox to install an actual browser on iOS. Firefox on iOS is just a skinned version of WebKit/Safari. See 2.5.6:

This is not the cause though - other third-party browsers on iOS can do ad-blocking, and also can use system-installed extensions.

They could also launch an alternative browser engine for iOS and iPadOS in the EU.

That's incorrect, and Firefox doesn't blame Apple for this. Many 3rd-party iOS browsers do ad blocking natively and/or via extensions. https://orionbrowser.com/platforms/ios
