“Last year, United States President Barack Obama issued an executive order that limited the business that U.S. companies could do in Crimea. This was part of an effort to indirectly punish Russia and its economy for invading the territory and annexing it from Ukraine. This led to corporations like Apple and Google pulling all of their services from the region, and now game publisher Blizzard has done the same. Crimean game fans can no longer log into their accounts for World of Warcraft, Hearthstone, Diablo III, and more.
‘In accordance with current trade regulations relating to the region of Crimea, we are legally required to suspend access to your Battle.net account,’ reads a Blizzard notice to players in the region, according to Russian gaming site Geektimes.ru.”
