Is Česká spořitelna ethical?

As the world goes to hell, there's a growing trend for people and companies to hold up their hands and say, "Hey, it ain't my fault!" Some of them go so far as to deny their past by becoming green, corruption-free or ethical. Česká spořitelna's pension company has done all three by launching an Ethical Pension Savings plan that won't invest into arms, tobacco, nuclear power, mining, food speculation, GMOs, companies using child labor or corrupt companies. "What's left?" you might ask. Oh, nor will it invest into U.S. T-bills or those of any other country with the death penalty. When the Norwegian pension/wealth fund excluded ČEZ early last year from its investment palette, it was a hypocritical case of fossil-fuel denial, but the fund was otherwise consistent in its application of the rules. What about ČS's pension product? How can it refuse to buy ČEZ shares, when its parent still does business with ČEZ? ČS's pension plan is ethically minded, but the bank itself isn't?
