1. It's very clear that his office has no qualms with filing cases that include untrue statements.
2. It's also the case that this group of claimants is strongly associated with a government official who is very angry at companies and has been trying to attack a communications law from every angle he has. One cannot help but wonder at the timing of all this.

I would change it to "Google, Facebook allegedly had illegal deal to rig ad market"
Sometimes this would be a technicality, for example where it's beyond much doubt, but in this case it seems that it's far from proven, so far.
At the moment, I have no idea whether Facebook & Google did this or not. Maybe they did, maybe they didn't. No judges have ruled on it yet. No evidence has been presented. Even the details of what exactly they are being accused of are vague. It's purely an allegation at this point.
