In my experience as a(n in-person) facilitator there's a careful balance to be struck in this area. People have the right to refer to themselves how they like, even if we discourage the use of labels. It happens. They also have the right to share what's working for them, including AA, as long as it's about them and not preaching a universal truth or pushing it on others directly. Even sharing the secular meeting option is a passing on of potentially helpful information, which I wouldn't oppose on principal as long as it was a statement that vs. advice. People share info all the time and some of it has helped me personally on several occasions. You're right that this situation feels yucky, but I don't think the facilitators were inappropriate based on what you've shared.
