You're changing the topic. You originally accused developers other than Apple of maliciously intercepting web traffic. I responded that your FUD is actually a greater concern with the closed source Safari than the free and open source uBlock Origin. What you're saying now about ad blocking coverage and web views is completely irrelevant to the invalidity of your original argument against an open browser ecosystem on iOS.
You are comparing a “web blocker” to a “browser” you are also waxing prosaically about how much better is and failed to show any examples.
The fact is that your ad blocking extension won’t work at all within embedded web views.
We know for a fact that a third party ad blocking extension can not intercept your web browsing history on iOS whether it is open source or closed sourced. It has no access to your web browsing history.
Your assurance comes from open source, mine comes from knowing that my third party as blocker doesn’t have any access to my web browsing.
The comparison is between Safari + Safari-compatible content blocking extensions and other browsers + fully-featured content blocking extensions (such as Firefox + uBlock Origin).
You have been spreading FUD about fully-featured content blocking extensions like uBlock Origin, which is not a very good argument because Safari itself is closed source and its behavior is opaque. A combination of Firefox + uBlock Origin is fully free and open source, and its behavior is fully and easily verifiable. It is absurd for you to criticize combinations such as Firefox + uBlock Origin when the combination of Safari + a Safari-compatible content blocking extension is clearly less transparent due to Safari being closed source.
Apple's anti-competitive App Store restrictions are preventing the superior combination of Firefox + uBlock Origin from existing on iOS. Fortunately, regulations will soon make some of Apple's anti-competitive restrictions illegal in some major markets.
uBlock Origin not being able to protect web views on iOS is yet another restriction imposed by Apple. If browsers on iOS were able to supply web views to other apps and activate extensions in those apps, as the Custom Tabs feature works on Android, uBlock Origin would have no issues blocking content in iOS web views. Don't blame uBlock Origin for a restriction that Apple created.
Until you use an app with a web view…
But tell me what can’t I block in your experience with 1Blocker on Safari?
If we are comparing ad blocking extensions. We know that there is no possible method for a third party ad blocker on iOS to intercept your traffic.
You’re comparing an ad blocker to a browser.
