This is only a reasonable stance at the very surface level.
1. "You either work with what we use" - so whatever organization you represent isn't capable of evaluating and shifting to more secure technologies?
2. "it is mostly unacceptable for an enterprise product to have opinionated decisions about what authentication it works with" - you think companies that care about security should not care about integrating with flawed protocols?
A potential customer making bad choices does not obligate a business to make bad choices for their business.
