Chrome and Safari; Chrome and Edge all use or used the same rendering engine (on one platform or another) for years, but you would never say you’re using one or the other when you don’t.

Similarly if my Chevy has the exact same engine as a model of Dodge I would never say I’m driving a Dodge.

But would you still call it a car?

I don't see how this means that Firefox without Gecko isn't a browser. I can see how you might take issue with calling it Firefox, but it's clearly a browser that's in the app store.

Thesus's ship has left the building.

I could see both sides, but ultimately I use Firefox as an attempt to try and keep chromium's monopoly as a web renderer at bay, even if for seconds longer. Firefox on IOS being forced to basically be built on top of a chromium engine defeats that purpose.

It's for similar reasons that I don't recognize "Visual Studio for Mac" as VS, but a rebranded Xamarin. It lacks several core features of VS that devs hearing the name would expect (let alone hundreds of more specialized features).
