Consultancy Costs Money
Companies trying to escape the consultancy overheads involved with "on-prem" think they can escape these costs by going "cloud". I suspect this is why cloud is in vogue at present.
I have seen this countless times with email: companies moving from a local email server to using a cloud-based one. It seems that cloud providers give no consultancy on issues such as "you might like to amend your SPF record if you want your emails to continue to be received."
