Tough question.
I do doubt that the US would allow a foreign entity to buy it given the volume of domestic infrastructure/organizations that are reliant on Chrome. It would carry an inherent national security risk, as hypocritical as that is for the US to say.
The other problem for an independent Chrome company is that Chromium itself is an unprofitable FOSS project, and Chrome only derives value from integration with Google services (as Edge does with its Windows integration).
It’s not impossible, looking at Mozilla. But it would mean Chrome would have to become a very different kind of browser.
The Edge relationship also makes things interesting, as presumably without continued investment from Google, Microsoft would end up becoming the primary maintainers of the Chromium project.
That’s just it. It’s fetishism, really. Tankies ignore the modern revolution for the aesthetic trappings of a failed one.
