> The point is that the entire concept of Google is about ranking (a form of discrimination) the relevancy of websites to the search query.
Not really. All you'd have to do is make the algorithm public, and become a commodity. When you're a common carrier, you sell bandwidth, not magic fairy dust.
> Common carrier status means that a search for "Microsoft official website" would not be able to prioritize Microsoft's official website, because that would be discriminating against all other websites that claim to be Microsoft's official website (and, by extension, discrimination against the people hosting those websites, who would then be able to sue Google for that discrimination).
This is absurd. Trademark violators can't sue for not being treated like the real deal any more than I can demand that my phone company say that all of my calls come from the White House. If Microsoft backs up their claims to all be official, then they all should be able to sue.
edit:
> Common carrier status also throws a giant wrench into the already problematic issue of content moderation.
No it doesn't, it decides it for Google. And Congress would be free to allow Google to do whatever moderation it wants, and this shitty court might give it even more latitude. Count me as someone who is perfectly happy with preventing Google from doing any content moderation not required by law. All of the drive to censor has been coming from Congress and the administration anyway; the real danger in the current climate is that Google becomes a common carrier and gets the analog of the Great Firewall dropped around it the next day.
