You are missing the point, Blizzard has as much choice in this as you do in finding a computer or virtually the majority products available to you made on state-owned slave labor that ultimately benefits a regime of military enforced might over its people.
Blizzard is owned by a another company that is making the decisions that affect their bottom line. That company - like the many companies around the world - has its finances directly connected with a company (actually several), from this same country empowered by its regime.
You want to blame Blizzard.
You’re pointing the finger at the wrong place.
You want to claim a moral high ground.
You actually have none.
