They must defend their trademark, and unfortunately, a lawsuit is the only way that the courts will recognize it. If they didn't, then anyone could use their non-response to the workbetter domain name as evidence to take their trademark.
It seems to me that if someone else was using the same name for 16 years prior to them and they claim that it's confusingly similar, they're effectively arguing that their trademark is invalid. Either they had a trademark and spent 16 years not enforcing it, or they failed to notice/mention prior art when they applied for it.
