Telefonica has nothing to do with the Pocket extension, they just (as far as I know) run the rendezvous servers that support the Hello feature.
Mozilla wanted to ship a WebRTC implementation, but it's not much use having webcam and microphone input unless you can send them to other people, and in this age of NAT and firewalls, that needs a rendezvous server. Mozilla had already had fruitful business interactions with Telefonica with FirefoxOS, and a telco seems like a reasonable choice for hosting a long-uptime network service...
In exchange for donating server hosting, Telefonica gets to display their logo in the Hello UI. I don't know if they also shelled out money in addition to hosting a service, but 80% of Hello's code is Firefox platform stuff (VP8 encoding and decoding, etc.) not Telefonica stuff.
