If you're using a product that does not make API calls externally with your data previously in a corporate environment that has very strict controls, and they add a feature that is part of the base install package, even if opt-in, that allows it to do that, and they do not have something like Group Policy hooks to forcibly disable it from on high, then they will block the product globally until the functionality is more contained to something their compliance systems can prevent, be it via a group policy hook or blocking the install at all.
Companies take "we might make an external call with your data" very seriously, and regardless of how much you trust the external entity, adding that in is rightfully seen as a very serious concern in some environments.
