However, if a third party service wants to run the Unity Runtime in the cloud with their additional SDK, we consider this a platform. In these cases, we require the service to be an approved Unity platform partner. These partnerships enable broad and robust platform support so developers can be successful. We enter into these partnerships all the time. This kind of partnership is what we have continuously worked towards with Improbable. is Improbable the only 'platform' affected by this change, or are there more 'reasons' (companies?) for what this change was made?
