In a setting where advertisers are effectively forced to use Google to avoid giving market share to competitors, there's the element of not having a choice while ending up with a significant disadvantage once these mechanisms falsely trigger.
With Google being the operator of the platform and judge at the same time, I don't think they can hide behind terms of use in all jurisdictions. Scaling up without carrying the costs involved seems pretty unjustified.
Some people would call that racketeering.
People might be afraid of lawyers but they aren’t involved in these processes.
