I don't think it's going to be bad at all. These are not irreplaceable things and they're not even the best options. Email, SSO can be found from many providers, or self hosted. Docs/sheets have lots of online and offline alternatives. There's at least 4 large maps providers including OpenStreetMaps. I think there would be some pain for a few months as other companies deal with the user influx and then we'd get over it.
