Completely disagree. This last March, Microsoft changed the storage limit per user on OneDrive for education from 1TB to 100GB, and users either had to delete a ton of files or pay for increased license/space. We ended up standing an on-prem file server back up shortly thereafter because we could not get our users and faculty to delete research data and could not afford to nearly double our cost expenditure. In my experience doing IT budget for years, cloud has meant that you cannot predict your yearly expenditures, Especially if you use your services that are funded in part by venture capital. Let’s say you start using some cool research presentation project and suddenly the economy dips and they lose funding, the cost goes way up. Life cycle management has gone completely out the toilets in my experience with cloud products.
