Don’t be patronizing.
Management needs to act, and locking yourself in, if it’s the only choice, go for it.
In the case of IT, composing across clouds is pretty common because it solves problems. Note I am not talking about brokerage or constant migration or other such nonsense. I’m talking about treating your clouds as a portfolio where you have levels of investment for particular reasons, and can make long run decisions about upping or lowering investment in. You compose across them. Salesforce for CRM, AWS for my front end apps, Google for my analytics, Azure and O365 for internal apps, whatever. It’s reality.
Forcing everything on one cloud, boy I donno. For an SMB, sure.
My point is, don’t tell me how tasty and good for me the shit sandwich I am forced to eat is. Users of EPIC hate it, that’s a market opportunity.
