It's not "sinophobia" to not be aware of games (or any kind of media) that only ever released in a certain language and only in a certain region, especially before the Internet. Nobody has ever been afraid of freakin' Taiwan, other than mainland Chinese kids after a fresh indoctrination class at school.
This does not just extend to games from Asia. The article mentions the European home computer scene from the '80s, but there are predominately European niche gaming genres that nearly completely passed by Americans, even if there was an English-language release, like for example the resurgence of point and click adventure games in Europe in the early to mid 2000s (started off by the runaway hit that was coincidentally called "Runaway: A Road Adventure", an equally excellent and obtuse title, sustained by regionally successful series, like for example the dark and moody - and kinda crappy - Black Mirror series or, more recently, by series like The Whispered World and Deponia that are just as good as the Lucas Arts classics that inspired them), mid-budget RPGs from that time like Gothic and the first Witcher that at best found niche audiences outside of their core central- and Eastern-European player bases and cheaply cobbled together, yet consistently best-selling German job simulators, the only true international breakout success of this genre being the Farming Simulator series. Honorary mention: The astonishing OMSI vintage bus simulator, which is at the same time very retro in terms of its tech, yet so detailed and realistic, it caused perhaps one of the strongest waves of childhood nostalgia I've ever experienced.
As for titles like Free Fire, not every F2P slop that finds hundreds of millions mostly bot users in Asia even deserves any attention to begin with other than as a cautionary tale of what the industry as a whole should not move towards. It wasn't "prejudice" that "erased" the Korean predecessors of modern P2W nonsense out of its nonexistent public consciousness in the West, but rather that these games were objectively terrible, sent the industry in a worse direction and, also only released in their home markets for many years, were only playable from there due to language, authentication and payment barriers. Terrible games with terrible business models that are only interesting as historic artifacts. When a few eventually did make it over to the West in the mid 2000s, they were rightfully panned for their predatory monetization and poor quality; I tried a handful back then and found that the reviews were right. These games flopped hard, but Western developers took notice, unfortunately.
The one good aspect about this preachy article that seems to be born out of some global South inferiority complex (seriously, just do your stuff without constantly wishing to be appreciated by Westerners) is the mention of the vibrant South American modding scene. On the other hand, I'm surprised, given that this article tries to at least touch on so many overlooked historic niches of gaming, that there's no mention of the Famiclone scene, which to many people in Asia and especially Eastern Europe was the first contact with videogaming after the fall of the Iron Curtain: Cheap, extremely low-quality NES clones initially produced by Taiwanese and Hongkong firms, sold through flea markets, with cartridges that contained increasingly bloated collections of pirated games, sketchy ROM hacks of popular titles and even some original games (virtually none of them any good, unfortunately). These are still being made to this day, but are now sold online to unsuspecting buyers looking for affordable retro systems.
Nintendo went even further than that:

And they absolutely have said that emulation is illegal in the past:

On their website, they name emulators in a list of "illegal activities" they want people to snitch on:
