Most of the effort behind Hello was independent of Hello. Hello is based on WebRTC, which is something Firefox needed to support anyway. Hello is just a neat way to use it, and I doubt that it required a lot of effort. ICBW, though.

Same goes for Pocket.

Little effort, but we (eg: the community) don't get anything that's reusable. We just got a bunch of code that interacts with some proprietary system.

Meanwhile, we still don't have any FLOSS implementation for WebRTC-based voice+video.

I can't figure out what you mean here. WebRTC's implementation is totally open source. The only thing aside from accounts in Hello is the STUN/TURN servers, and I think OSS projects exist for running those.

In other words, everything is reusable and is being used by tons of new startups and projects doing video conferencing.

The whole thing will even use free codecs if both sides support it.
