Also about Ichigo using it. Maybe, like you said Ywach can control other quincies abilities and when Ichigo came into contact with a quincy under Ywach's command he awakened his quincy powers only because he was curious to see what he could do. Maybe he awakened them just to get a feel for what Ichigo was capable of.
