The engine is a method for apple to maintain control over the entire ecosystem. Is a web standard developing which could threaten native ios apps? By maintaining control of the engine they can prevent the standard from threatening them.

Users dont care about the engine until they cant use some web based thing because apple has decided so.

In this case, it's more like telling people that a particular Toyota was built by BMW.

It might not seem relevant on the surface, but the underlying technical differences could pose an issue for certain user cases, thus it's an important consideration. Not all Firefox addons work with the iOS version just like not every Toyota dealership carries parts for a Zupr4.

That's a debatable point but the result either way doesn't change the point of my comment. They were dismissing the parent comment because they didn't understand the true nature of what they were talking about.
