As long as this remains an impossible question to answer then they should probably pay the least amount possible.

I'm all for improving current tax regulations, but first we must agree that the problem is with the regulations.

They broke the law. They lost. That's what the courts determined.

What, do you not believe in the law or something? Because this is what the courts did. They said that blizzard was guilty, and therefore I judge them as such.

That is not what the courts said.

"In the United States, Activision Blizzard has recently settled a transfer pricing dispute with tax authorities for $345m"

It looks like Blizzard was guilty enough of tax evasion that they had to settle the case for 345m$.

If you have to settle a case for 345m$, then you are guilty enough for me to condemn you.
