I think the main problem with Google (and perhaps part of the reason why Google is great in the first place) is that Google relies too heavily on algo solutions and when the algo makes a mistake, you cannot get to a real person for support
Additionaly, Google Workplace (or whatever it's called next week) is particularly unsuited for enterprise because even when you do get a hold of someone, they aren't willing or able to provide enterprise level support.
For example, we were getting a lot of spearphishing, so we wanted to disable links in inbound email; can't do that. Then we were aquired and wanted to merge our account into our acquirer; can't do that either.
That something's called PRISM.
