I don't think Chrome is a very popular browser for desktop Linux users. Or, at the very least, it is definitely not as dominate as it is on Windows and macOS.
There is alternatives for now. But if Google has to sell off Chrome, they will also be less motivated to pay as much for Firefox as they do now. Then what is remaining for Linux if the Chromium reskins are gone? Webkit builds?
