That's what I got from my read of this text, I can't figure out how someone else drew that conclusion.
I didn't enroll specifically because I assumed it might waive my rights. I didn't notice any such disclaimer on the am-i-impacted lookup.
If it really does apply to the lookup itself (or was intended to apply), then it's worth some outrage. If not, it's worth significantly less outrage.
EDIT: The authoritative-sounding @pabloishappy says, "I spoke with equifax rep named Marvin. He said enterining your last name and 6 ss#'s DOES NOT constitute enrollment. Yiu neednto complete1/"
EDIT2: per https://www.equifaxsecurity2017.com/frequently-asked-questio... "The arbitration clause and class action wavier included in the TrustedID Premier Terms of Use applies to the free credit file monitoring and identity theft protection products, and not the cybersecurity incident."
