don't act like your decision is the epitome of morality and tell others to do the same.

Even ignoring the current situation, Actiblizz was never made by saints.
They are guilty of tax fraud (included paying nothing in the US but getting tax refunds
from the country, so if you are a US citizen your taxes are actually going to Kotick) mass layoffs to boost the administration's profits, severe mistreatment of the workforce with crunch time and so on. (The latter being legal doesn't make them good by any mean)
Giving money to these companies is like buying the bullet that will hit you. Same goes for all other behemots like Amazon and such.
