You realise other browers can also opt out of this feature right? Why did you even use this example if you have this feature, I mean keylogger, also in brave? Your responses here are not necessarily helping you or your product.
I'm aware you can opt-out of this in other browsers, but the default is to emit user input to Google, without the user being made aware. In Brave, if you wish to send your keystrokes to a third-party, you must opt-in. That's the key difference here.
