I think there's some truth to what you're saying here, but there is room for some nuance.

In the US context, you should refrain from blaming specific people and if you possibly can you should explicitly leave open the possibility that everyone involved was trying to do their best (even if you really don't think this is true). Project an assumption of good faith even if it's not deserved.

But that said, you are looking for a new job and no one is going to be surprised to hear that there were things you don't like. More importantly, it's valuable to surface those things because you want to know if the things you didn't like are commonplace in the place you're interviewing.
