By a huge margin the two biggest Linux clients of Drive are Android and ChromeOS. "Actually linux" is literally 5+ orders of magnitude smaller. Google maintains and updates 99.999% of Linux drive clients every month.
For what it's worth, Anbox/Waydroid can run the Android-based GUI quite well. The Android subsystem doesn't integrate too well with native applications, but for things like basic sync and even document editing it works, at least.
In truth I'm not really looking for a solution. I was snarking really. I was a consistent user (and paid for Google One) until they removed the Google Photos integration, which killed much of the point of it for me.
