The fact this person could not get an attorney to represent them says a lot.
I know someone suing their landlord and he had to find a lawyer 3 hours away because all the local lawyers work with this property management company.
What lawyer wants to have their pay limited thusly?
You can hire your own lawyer for the proceedings but no jackpot payouts in arbitration.
This shift happened 2022 ish.
Almost every tech company still uses them.
