For a long time, GUADEC, Gnome User and Developer Conference, was supported for video recording by Collabora and other smaller free software companies which did the heavy lifting in Gstreamer too (a/v framework that's the base for GNOME apps). My apologies if I am misrepresenting who did what, maybe it was Igalia or another company: this was 15-20 years ago. How much of the actual video recording equipment was coming with free firmware — probably none — does not change the fact that these are people improving the situation rather than just accepting that the hardware you buy is at the mercy of the original vendor.
