I agree. If Chrome is sold off, the new owners might think its uneconomic to maintain a (desktop) Linux port, keep it open source, or they might make it even less standards based than it is now.
And those users can then move to a browser that isn't screwing them over, that does support Linux and open source and web standards. Google Chrome is not the only browser possible except to Google shills and sycophants.
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.
