One problem with the "Petrov day" ritual that has been created seems to be that in addition to the virtues 1 & 2 from the Petrov story someone arbitrarily added virtues 3 & 4 (and ignoring others virtues related to Petrov such as not abiding to social pressure) which somehow contradict his values:
3. Not taking unilaterally taking large (and irreversible) action
Petrov took unilaterally (and arguably large) action!
4. Cooperating / being the kind of person who can cooperate / being the kind of community that cooperates with itself, especially when the stakes are high
Petrov did not cooperate with his peers. He deliberately had to be non-cooperative to achieve what we are celebrating him for!
