Agree. I sell simple sass product myself and offer SAML to everyone. I view security as a basic right, not something to be used to extract more money for. Charging for additional features is ok, charging for keeping your account more secure is just plain wrong.
SSO is a security feature, not a convenience. It happens to be a security feature that comes bundled with some extra convenience, but it's not the only one like that; so are password managers.
