Sir Tim Berners-Lee, inventor of the World Wide Web and HTML, has expressed support for compelling Apple to allow other browser engines on iOS, as more competition leads to more innovation and bright ideas. He also states that having a powerful browser on iOS would "change the dynamic" with respect to web app's viability on mobile.

Fully agree. I personally had clients backing off from entire projects due to not being able to ship some native like experience on iOS, only Android, for example the prompt to install as a progressive web app.

I'm tired of losing sales due to that. And clients needing to increase their costs massively due to that.
