That might be true for a technical user, but is the average user going to know that discord is broken because they disabled webrtc? Also, resistfingerprinting is going to significantly increase the difficulty of recaptcha challenges you encounter.
I wonder just how much security relies on tracking. I know my VPN makes captchas an absolute nightmare.
I always have a hard time using some services when in incognito mode; I get the captchas, and either they are wrong or are really hard, and it can take several tries to get through them.
Because an error message should be displayed then.
