So if each individual choice is reasonable then is not the sum of the choices reasonable?
Yes it would be. But that's not what happened. What happened is not that everyone made one choice or another. What happened is that some people tried to get the whole community to refuse the choice itself and play as if the choice never existed.
If the rule had been Age of Entropy for example (I'm on team Entropy), then maybe I would have considered upgrading some Dissipation Shields into Dissipation Fields ... but then realized that Dissipation Shield (which blocks damage using Entropy quanta only) could be better for me. So I would
choose not to upgrade my cards. That would be fine. However, in this revolt, players would want me to ignore the rule altogether and not consider the possibility of upgrading my cards. Yes the outcome might be the same but the way of getting there is completely different. And that matters
a lot.
This is not about outcomes, it is about intentions. A large part of the community had a completely wrong set of intentions, which was to flaunt authority, taking action into their own hands that they had no right to take.
