My parents had an uncanny knack for always buying slightly the wrong thing when I was a kid. Betamax, Amigas, minidiscs. I used to have a cassette player that had a tape recorder on it. It made it bigger and heavier, and probably more expensive and I never used the record feature. Just because part of the product works well, doesn't mean the rest of it is good.
That's a bad and misleading comparison here though. Your cassette player had to add the bulky recording feature to become a recorder, but did not need it to be a player. Firefox is a webbrowser, not a video conferencing software, but it had to add WebRTC to be a web-browser (the bulky bit), so adding in recording is trivial. A more honest analogy would be saying you had a cassette player that already had all the hard…
1. The Walkman was born after a Sony exec had started using a Sony Pressman tape-recorder intended for transcribing meetings/interviews to listen to audio tapes while on planes. They took out the recording functionality and speaker (while adding stereo to the headphones) to make it smaller/cheaper/more portable.
2. Firefox was born after some Mozilla devs took the full featured Mozilla suit and simply hid a lot of the features (email, HTML editor, NNTP newsreader). They later on actually did the work to remove unused code, but at first it was merely cosmetic, though everyone likes to believe there was a mystical time in the past when Firefox was a lean, mean, codebase rather than a minimilist reskin on top of a lot of bloat.
Not sure how that relates to WebRTC, just thought the parallel was amusing.
