So just a hunch.
More like a prejudice. If we don't like the outcome, obviously the process was wrong or non-existent or they "didn't try" or "didn't want to spend money". It is impossible that people could have made a bad call after doing everything right. That is the essence of bad faith.
Yes, assuming good faith from WelNix is in itself an unsupported assumption. But I think it's an assumption consistent with my mental health and a sunny disposition. If you like to assume that screw-ups are due to incompetence or even malevolence, rather than bad luck or best-of-bad-options, then the angsty discussions will continue, no matter if we win the league next season.
Some people aren't happy unless they've got something to be unhappy about.
