Maybe.
But when the parties of the lawsuit find their credit rating destroyed...
OK. I volunteer to be lead plaintiff. I am a retired old guy living off SS and pensions.
I don't really give a rat's rear end about my credit rating -- it is convenient to have credit sometimes, but not necessary.
And, best of all, if Equifax reduces my credit rating due to me suing them over their data breech, the punitive damages award will be astronomical. There will be line of lawyers a mile long wanting me to sign up with them.
