They use ChromeOS as well, this article focuses on those people who want to use a mainstream Linux Distro at Google.
Pretty much everyone has a gLinux workstation or logs into a gLinux VM - they were, traditionally, the only devices that had access to the main source repository, so it's not so much about whether people want to or not.
This has changed/is changing. It heavily depends on your team (especially if you're not in engineering, I don't think most non-engineers would have a gLinux machine or a workstation out of the box). We've developed tools for crostini that would let people access a gLinux environment, I don't know how much I can talk about it so I won't go into details (although it's nothing super secret either), but the bottom line is that more and more engineers these days are able to do 100% of their job on a ChromeOS machine, including dealing with google3 stuff.
