Regardless of which CAD system used, be it Altium, Mentor, Cadence etc. I cannot see that any large organization like automotive would be willing to use a CAD-system that relies on parts of the user data stored "in the cloud". Given the fact that hackers have been able to penetrate even the Pentagon, imagine the consequences of a security breach where data is spread or destroyed at any given time. In my opinion, the use of a CAD-system has to be able to be maintained internal to an organization without any data transfer to an outside service. Be it license servers, data storage or anything else.
