ffmpeg contributors required to run non-free software

Some ffmpeg contributors in some situations are forced to execute non-free software. Specifically, if a Tor user attempts to register for an account on in order to report a bug, they are forced through a reasonable CAPTCHA (it simply asks a question like "how many wings does a bird have" and accepts freely typed replies). After completing that CAPTCHA, the user must fill out a registration form (username, pass, email, etc). Then after filling that out, Tor users are denied and given a Google reCAPTCHA.

If the user does not execute Google's non-free javascript, they won't even know that an additional CAPTCHA is presented. They simply receive "CAPTCHA error". Upon running non-free javascript from Google, it then becomes apparent that users must solve a reCAPTCHA.
