And at this point, I'm not sure what you expect them to do. The time to roll back is gone; if that happens, it needs to happen within 24 hours, and that window has passed.
Realistically there's not much to be done about it at this point. A segment of the players got a boost, some a small one and a few got a really big one. It is what it is, and it's frankly too late to do much about it.
It doesn't actually change a whole lot about the game though. You were already either facing guys with maxed bases or you weren't. There might be a few more of them now. So what? They're distributed among alliances, so it's not like the benefit was concentrated, and will result in unfair advantages.
The effect is frankly no different than a a small portion of the player base going on a spending spree. You'll likely not even notice it in practice.
