It might help to know that many universities can't just use cloud services willy nilly. There are only a few people on campus that are technically allowed to agree to a license agreement (doesn't mean others don't, but for something big it becomes important). Those license agreements have to go through significant negotiations to ensure all requirements for state laws governing the university are met, all NIH or other grant requirements are met, etc. Just the contract negotiations alone can take a year or more, if they can ever come to agreement on terms. This is definitely one area that companies, that have the ability to make their own decisions, can move around and try different services much more quickly. Universities and medical organizations have much more stringent data requirements than most businesses.
