I mean, from a business perspective, his departure is likely not a loss anymore. Star riders generate publicity, but, for the team as a business, the point of generating publicity is to create value for the team's sponsors. Bahrain Merida might have been hoping they could turn this around and get him to commit to riding the Warp, at the very least, for next season. Otherwise, his departure is actually a win for them financially. He is literally generating negative publicity for both Merida and Rudy Project, the latter fairly intentionally and overtly.Bahrain-Merida Team should sort that out.
Dennis' departure might be a bigger loss than expanding the frame range or any other piece of equipment.
I would think that today was the day he crossed the Rubicon. At this point, the team could be destroying its own reputation, with not only their current sponsors but any potential future sponsors, particularly equipment sponsors, by continuing to support him. Ironically enough, if team management can leave their own egos behind they probably should try to give him a sweetheart send-off in exchange for some kind of commitment from him to stop trashing their sponsors. Maybe there are other considerations at play, but the way I see things right now that might be as close to a win-win for everyone as you can hope for.
