However, as reported in Vietnam.net, it's possible Steam has been taken down in Vietnam after local game developers complained about the scope and size of Steam's vast portfolio of games, claiming Vietnamese devs cannot compete with Steam's releases given they are subject to government approval and thousands of international games on Steam are not.
Citing it as "an injustice to domestic publishers", Vietnamese studios reportedly say that local game development "will die" if Steam is able to keep releasing games without the same government scrutiny as domestic games.
Based Vietnam protecting its domestic games industry from American capitalists. :)
TLDR: the online game monopolies of Vietnam complains that they can't extort the market share our Lord and Savior Gabe Newell rightfully earned," said one unhappy Steam user.
Steam users are so fucking insufferable. They hate all capitalist game companies except this one which they will eagerly lick the boot of.
What I've seen says they can still use the library they have bought but can't use the store etc.
I did only hear from one guy when I asked about this, so I'm not sure what the full extent of the situation is, but aforementioned singular Vietnamese developer called the provided explanation a "very wild theory" and that the quote seemed to just be speculation from a random guy, "...and as of today, people can access Steam normally."
