Cyanogen Inc, the company founded to do commercial work on it and running a lot of the project infrastructure, ran out of money after some weird things like cancelling a licensing deal with OnePlus suddenly and closed. community part of the project rebranded to LineageOS

just to be specific, they licensed the exclusive right to the cyanogen name in india to micromax (while previously licensing the non-exclusive right to oneplus in all regions), who then got an injunction against oneplus selling their devices in india.
