They probably mean the old desktop one that has been re-branded to "Google Earth Pro". The UI looks a decade old but it's still useful for doing more advanced things like taking measurements.
FWIW, I use Google Earth Pro on Fedora quite often, and I'm deeply appreciative of the work it took to make that such a simple and enjoyable experience.
I hate that the vocal and tiny minority of linux users who are never satisfied are the ones that most people hear from.
