I don't know, nobody criticized anyone for attacking the Bankai stealing enemy with Bankai, not quite the smartest move. It sounds more like he's complaining that Gotei 13 was unable to stay ground against a vastly superior force, which the Quincy clearly were (if only because of Bach alone), and that's just unfair. I generally hate it, when people do that:
being douchey to someone, just because they lost a fight against an adversary he/she/it had no chance to defeat in the first place.
Because the 4th was forbidden from leaving their place. Yamamoto's orders were kind of stupid. There probably would be fewer deaths, if at least some of the medical personnel had been outside.
