Because you don't always get a choice. Not all developers have the resources to make special UIs for iOS/Android/Windows/Mac/Linux. Sometimes it's either PWA or nothing. (Well, I know there are other cross platform technologies, but IMHO they're all even worse than PWAs.) I have an app like that... I make it by myself, and I have no desire to make 5 different GUIs. And yet thousands of people on iOS use it as a PWA. That seems pretty pro-user. The downside is, my app performs worse in Safari than any other browser, so these iOS folks with high end iPhones are getting about the same experience as Android users with $100 phones. I bet I would have even more iOS users if Apple let them use a better web browser :)
