I don't see Jolla doing it too. Yes there are few fellows that are from Jolla here (most of them were here before Jolla). Yes we speak here about Jolla. But AFAIK Jolla refused to use TMO as something related to them.
Same as there are Tizen(there are guys here who participate), Ubuntu(few members here now work for them, btw including ex-intern from Jolla) or even WebOS discussion. Just happen to be, people here more interested in Jolla and there is no more useful and comfort platform to discuss(TJC is not that), while tizen and ubuntu have a lot of other places.
