My comment said, show me that the Google deal with Reddit is exclusive.
You haven't done that.
And there's no reason to think it would be, because of antitrust. The DOJ doesn't have to act "immediately", the point is that obvious antitrust violations come with fines that make it unprofitable to attempt in the first place. And this would be black-and-white obvious antitrust violation, given Google's monopoly status in search. This isn't a gray area where it might be worth it for Google to roll the dice.
clearly some deal was reach between the two parties or we wouldn't be here.
whether or not the deal is exclusive OR companies have to pay to index reddit it's still bad for competition. money has a barrier to entry preventing newcomers.
I can blame reddit for creating the deal and I can blame google for accepting the deal if the effect is bing, ddg and others cannot display reddit results without reaching some deal.
Blame Reddit, not Google.
