Apple's original position on third party apps was that they deserved on the web, in what would eventually become known as "progressive web app" form. That position was abandoned not just because it was a mediocre user experience, but also, it actually prevented device lock-in, which is something Jobs obviously craved.
You can argue that some apps are time-sucks, or bad for your overall well-being, and I'll be right there with you. But that has relatively little to do with whether they're shitty web apps or native code apps.
And also, the fact that smartphones do way more than originally imagined is a great thing. In most parts of the world, I can pull out my phone, tap a few characters, and a car will magically pull up where I am and take me wherever I need to go. Or bring me food. I can translate anything to anything. I know the second a flight is delayed, which lets me be more present in life. My life is assuredly better because my smartphone is turing-complete and runs third party software.
