So when I use, say, ffmpeg: In what sense am I their product? They don’t collect telemetry, they don’t serve me ads, the output can be used with any other tool so there’s no lock in, there’s no FFmpeg Pro (TM) with features withheld from the base version. This seems a little silly I know, but GP was talking about open source projects and you literally said “I can’t find any exception”.
