Fallout from #BoycottBlizzard, game companies warn pro players/staff to keep politics private

Last night, League of Legends developer Riot, which is owned by Chinese tech giant Tencent, issued a statement revealing it had "reminded" its casters and professional players "to refrain from discussing any of these topics on air".

Meanwhile, the CEO of world's largest esports firm, ESL has warned staff not to discuss the Hong Kong protests on its social platforms.

In contrast to Riot and ESL, Fortnite maker Epic Games, which is part-owned by Tencent, said its players are free to express their views.
