it’s a perfectly valid reason for not using Firefox, my point is that they’re on the wrong platform. It’s the user’s own fault, because they chose a closed platform like iOS. Developing free software for iOS is a waste of time, since everything is under Apple’s tyrannical rule and they get to decide which web engine you use, they can disallow extensions and make it very hard (and against their ToS) to sideload apps.

I don’t like Mozilla at all, and that’s why I use Firefox derivatives and not Firefox itself, but I’m glad they don’t waste time developing for a re-skinned Safari. Those resources are best used in their own web engine.
