I think it's foolish to shoot down advantages in practicality and fluency of use on the basis of a decades long event for the vast vast majority of use cases. My company hasn't been around for decades and we don't use any particular spreadsheet outside of a select few for more than a couple months at a time. You'd lose all credibility arguing against G-suite on the basis of losing your data/getting your enterprise google account banned, because it would cost the business so much time and confusion relative to the ease of cloud solution.

I've already had disks fail, never had an issue with Google Docs being down, and if it happens I think it will have been worth it.
