While the grudge against Apple is real and has been discussed time and time again, the revenge described here is a joke: no-one will seriously use a web version when an app is available, the experience is really not as good, the findability is not there and for many apps device-features will be missing.
When given the possibility, I always use the web version over a native app. I do not want to install as few software as possible on my device, and (at least for the time being) the security model of the browser is well-known and customizable (to an extent).
I used to agree with this. That was before I developed the web version and was able to compare real performance. Web (WASM) beats both Android and iOS native apps. Only downside is initial data transfer (1.2MB). A bit funny since the iOS app is 20MB and the Android one is 5MB
