I think it is unlikely you would lose this domain in UDRP. The domain terms are generic in nature and it would take considerable time and promotion for them to establish their "products/services" as distinctive ... and by extension be able to defend some claim of exclusivity to the wordmark "freeones". My guess is they'd have a long road ahead trying to establish rights in this name.
"Free ones" can be about many things which are free to consumers. They have no brand - LOL.
