Except for "visitors to the zone", they literally only measured the things that could be positive. There was no world where congestion pricing was going to increase number of cars. Actually yellow taxis are up, which they portrayed as "green" but I think most people would argue is actually "red" - i.e. we want to lower the number of taxis (and rideshare).

The controversial questions: restaurants/businesses, effect on low-income commuters, are all in the "Too soon to say" category. They're not even measuring the all-encompassing commute-time question which is "average commute time for all commuters", not "average commute time for X category". It's entirely possible that commute times for both cars and transit could go down while the commute time for an average person goes up because more people are being pushed to longer-time commutes.
