Competition. Google is able to use its power to push out competitors. Without that power, there would likely be lots more companies challenging the various product categories that Google currently dominates. Not every company would reach the same decision on all these issues, especially if these companies arose in different cultures.

presumably those smaller companies would be beholden to the jurisdictions they're located in, where the laws are drafted by people who are democratically elected.

so, i guess democracy would have been achieved. or at least a relative increase in democratic control

well at the very least the companies in question actually reside in the jurisdiction in which they serve and are thus at least in some form accountable to the people and hopefully share some values.

Being German I'm kind of tired of the fact that American social media sites have for some reason exported QAnon protests to our cities while women get banned for showing a nipple.
