It's not just the doomsday scenario. It's smart to avoid vendor lock-in because eventually a competing cloud vendor could offer better pricing or more reliable service. Or you could run redundant infrastructure on AWS and Google Cloud Platform at the same time to insulate yourself from major vendor outages. Also, not all doomsday scenarios are terribly far fetched. AWS might one day have to discontinue a service after losing an intellectual property lawsuit, for example.
