In the end I don't think it matters who calls out what, or whose responsibility it was to do XYZ, it seems to me that no one communicated. Things were going wrong, no one talked about it, or tried to fix it. No one said 'how can we do this better' or 'is there a way we can make this better' or 'can someone call out this'. You are correct, rage quitting is not the answer, but neither is ignoring the problem and allowing fails to continuously happen without offering advice or looking into the issue and improvements as a group.

You even admitted that another member offered TS to improve communication. But you said nothing, figuring if it wasn't a personal invite to you specifically you were not needed on. But you never asked if you were needed, or told them that you could not come on TS, regardless.

As I said, everything else aside, the over all issue I see is lack of communication from all sides. Of course nothing improved, it doesn't seem like anyone tried for the most part. I give props to the one person who mentioned TS though, at least they tired to help the issues in some way, even if ultimately it still failed. So I say yes, it's not any one persons fault. I feel it was the whole parties fault for not saying what was needed and discussing who should do what role within the party.
