The actual lawsuit does mention the cookie practices, it's the core of their class action.

My understanding of US law is extremely limited, but seeing it's a class action, would the lawyer be able to file the suit on behalf of the customers instead, if e.g. they thought it has a better chance to succeed as such? And if not, is the fact that this suit is filed on "breach of contract and unfair practices" claims presenting any evidence that Honey engaged in a specific legally defined practice of "cookie stuffing"?

I see. To be clear, I’m not saying what Honey did is not criminal activity, I’m just saying what they did does not look to me as if it qualifies as “cookie stuffing”. It might still be illegal, for a different reason. (Obligatory IANAL.)

This thread has started with GP saying "cookie stuffing is illegal" and me replying "does this qualify as cookie stuffing?" I'm not claiming what they did is legal, I'm claiming it might be illegal, just not for "cookie stuffing". As far as I can see there is no evidence that this particular suit claims "cookie stuffing", so there is nothing in it that can add to the question whether this qualifies as "cookie stuffing" or not. Which was my only original question.

More to it than that, alleging unjust enrichment among things in the latest amended filing: https://storage.courtlistener.com/recap/gov.uscourts.cand.44...
