Blizzard Entertainment

Blizzard Entertainment's reputation collapsed faster than any studio in gaming history, falling from beloved to infamous. In 2019, the company banned a Hearthstone player for voicing support for Hong Kong protesters, igniting international accusations of censoring political speech. The disastrous 2022 mobile launch Diablo Immortal generated over $100 million in revenue yet received a user rating of 0.8 on Metacritic, proving corporate greed overshadowed quality. Overwatch 2’s canceled PvE mode broke explicit promises to millions of players, while the explosive 2021 California workplace lawsuit revealed systemic harassment and pay disparities affecting over 1,000 employees. This scandalous trifecta — censorship, broken promises, and workplace toxicity — makes Blizzard more controversial than Embracer Group (#10), whose sins are mostly financial rather than ethical.
