The paradox is the sunken cost of your product easily becoming coupled to the cloud. Moving office is relatively simple, you call a moving company to lift all your chairs, print new business cards, hire a bigger maintenance crew and it's done within a week. Moving cloud could in worst case mean a 6 month complete rewrite of your core product depending on how much dependent you are to CosmosDB, Lambda or other shiny AWS stuff. You could say buying a machine you previously rented is the same thing but when looking at code migrations, rewrites and launching new infrastructure cost time from R&D, not just money.
