Yes but let’s remember everyone that Apple did their “best” in this. If a developer makes a browser that doesn’t use WebKit, then can publish that version only in Europe. For the rest of the world it’s still forced to publish the usual “Safari skin”. Basically doubling the work and the monetary cost of developing a browser.
The average people don’t know the concept of browser. I saw people using Google search (the app) as a browser. I saw people trying to login in their webmail using Google search (the app), then in order to see what photo they wanted to upload they went back to home by closing the WebView, watching the photo, then using again the Google search app to login in their webmail. Extremely infuriating, I wanted to die.
