I can understand his point about users being the problem - although that doesn't in any way excuse the banks - but criticizing her specifically is completely ridiculous.
It reminds me of how I hear people in my country commenting to each other about how nice is that politician because he rides a scooter instead of a Mercedes, while he and his party continue to sell out the country to big companies.
It's an irrelevant, stupid detail that detract from his position and makes him seem like an unreasonable person.
