Ok but which Linux? Ubuntu? Fedora? Mint? etc... Which desktop should they integrate with? Gnome? KDE?

I suppose they could go the Steam route and only support Ubuntu, but then that would be Ubuntu support, not really Linux support. It would be nice to have at least some support on Linux for sure, but unfortunately deciding to support Linux isn't an answer to a question, it's opening a whole extra big bag full of knotty questions.

Until that issue gets sorted out in Linux land, providing first class Linux support in any professional, commercial grade application or service is going to be problematic.

Insync is a Google Drive client that has been "providing first class Linux support in any professional, commercial grade application" for years. Also, what do desktop environments have to do with Google Drive clients?
