So extending this logic to other platforms: if Chrome has a security bug on Windows... you believe people will blame Microsoft? And you think that would be valid justification for Microsoft pushing a "security update" that uninstalls all competing browsers and replaces them with Edge?
If you made a "Microsoft Windows Desktop Citibank App" from Edge, and then in stall Chrome, and the Uber app now uses Chrome, and a bug in Chrome lets someone steal your Citibank info, yes, the user probably would blame Microsoft as it was Windows software which made the Desktop app for Citibank.
And yes, if Windows had this feature and then Europe demanded it work like I described, Microsoft would be acting reasonably if it disabled the Desktop App feature in Europe.
Apple doesn't disable competing browsers, it just doesn't allow different web engines to underly the browsers. You can argue with that but it isn't the same as "uninstalling all competing browsers".
