This would be so good. As someone who fully switched to Firefox on Android I hate that chrome webview is a thing.
Closest without rooting is to “uninstall updates” to the chrome app in the menu which makes it “APK Stub” instead of Chrome, ans then disabling Android Webview.
Why is you explaining it breaking the law? Can you not mention sanctions either? RuTube is also already a thing, it started in like the earlu 2000s during the brief Russian tech boom, alongside VK, LiveJournal, Ozon, avito, mail dot ru and Ramblr which were all the same thing - copy of a western site with some changes.
