I haven't seen where her vote is, but my strong read was directed to her initial position around Ekko - you said it was a defence, when, while it can be so, it's just as plausible that it's there to provide some nuance to what the actual argument against Ekko is.
I don't hate her vote off of her stated reasoning - she concedes that Ekko can be scum, then saw you tie her to him, in a way that she says makes her think you might know what Ekko would flip. It's not unreasonable then for her to see that, and suspect that you and Ekko are scum together. Further, Ekko has a wagon on him, so supporting that wagon isn't outrageous either, especially if Ekko is town, her basis for suspecting you falls apart too. It's not a bad line of logic, it's not that I necessarily subscribe to it all, but I can see and understand the thought process.
