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 trac.ffmpeg.org 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.
