The fear is that Google might turn Gmail down? Seems implausible, no?
I agree with you on drive, but docs is missing lots of features compared to msoffice (macros, excel functions, offline storage and runs) and google hasn’t been building tons of stuff into docs for a while.
I think they are fine for small orgs, but big orgs pay for lots of support and customization.
Not really. All it would take would be liability for privacy violations.
They can't be turned down for any reason. End of story.
