There are several problems with tolls (privacy invasive, collections infrastructure eats an unreasonable proportion of the revenue, etc.) that should cause them to never be used, but the relevant one is putting a disproportionate burden on travelers from outside the jurisdiction. Tolls that only pay for road maintenance and aren't intended to deter travel might not do this (even if they're still net-negative overall), so there is a stronger case to be made that they should be allowed, but the purpose of congestion pricing is explicitly to deter travel from people who for any reason can't use mass transit, and those people are disproportionately from outside the jurisdiction. If that was their actual reason they would be doing exactly this. Though they should still get rid of the other tolls.
