And the Office package is a very attractive offering. $36 / user / month and they get managed emails, chat, office, SSO, cloud storage, Windows, etc - basically everything that used to be the domain of a sysadmin.
The competitors are all fragmented; Google probably gets the closest but doesn't have a chat service like Slack, Teams or Discord and doesn't do hardware management as far as I'm aware unless you use Chromebooks.

Google is up to a dozen versions of chat, the current incarnation is called Google Meet which includes a video akak Zoom type service as well as a Slack-type chat service.
