> I can quickly and easily make an app for myself and my family that works without having to provision their devices or pay a dev license to Apple. I also use it at work for internal apps.

This is exactly why they don't want it. Some will say it's because those are Apple's users and Apple wants to ensure a great user experience and doesn't want unapproved things running on their devices, and others will say it's because it skips Apple's 30% take and their gatekeeping process. My opinion is that both are true, and conveniently both are achieved the same way: by making PWAs enough of an annoyance to both developers and users that they will voluntarily steer away from them. Classic game theory
