In an app, undoing that is pretty much impossible (or at least, above my pay grade).
This is one of a million reasons why apps are so bad.
In my experience it is above the average user's pay grade to work around it in a browser too. Even power users will probably give up if the usual ways don't work out (holding alt, browser extension, reader mode). The power-est of users might glimpse at the inspector, but they'll give up if the nodes are obfuscated.
All this to say that with things like Circle To Search or Apple's built-in screenshot OCR nowadays websites and apps are finally on a level playing field when it comes to anyone being able to circumvent text protection.
Just push the button to go to the task switch view and as long as the window preview thumbnail isn't blanked out, I can just get the phone to OCR any part of the screen in real time.
