Nothing, sorry - was using the past tense thinking about when the decision was made a while back. Omni seems to be getting more traction of late with people concerned about the CM issues. They are still GPL and that probably acts as a fairly decent barrier to any kind of acqui-hire attempts. Also having a diverse range of contributors (many with good jobs) helps there too, by making it very expensive/complex to try to get enough people onboard.

In an ironic sense, the argument used by CM was "CM Inc is different from CM community", and I think that was enough to keep some of the alternative ROMs pretty small. Sadly though, it has now emerged CM community was indeed a subset of CM Inc, and not so separate after all.
