Linux marketshare is around 1.5%, and I'd speculate those choosing Linux tend to be less willing to trust google/the cloud with their data than average.
It's just not worth it when the best-case outcome is indistinguishable from a rounding error,
You are talking about individual deployments where plain market share is reasonable. I'm talking about group deployments where multiple people need to work together. In that case the solution has to work for everyone.
