The whole point is to change behaviour, not raise revenue (although that's obviously something city leaders look at with glee too). If you shift the cost away from the people making the decision, it's not going to change behaviour. Congestion pricing explicitly wants to move people to transit infrastructure. More people using buses allows buses to be more frequent which is more convenient, reduces transfer times, and reduces the impact of outlier slow buses. My understanding is that the NY Subway is near it's trains/hour capacity otherwise the subway would also be able to benefit (although with subways the reliability thing goes in reverse because a stuck train blocks others vs a stuck bus being saved by other buses).
