I don't think you was the asshole, but I think (i.e. in my cultural circle) that's too public. I would send this message only to the person responsible, and if necessary sent a much softer message to the team like "I noticed that recently we had some merges without a proper review. Please avoid this in the future, code review is a strict requirement in our team".
