South Korea was the first country in the world to implement an internet censorship law. There is a historical record of censorship, regardless of which administration—left or right—was in power.
That said, it’s a complicated issue because these censorship systems also tend to create state IT contracts and job opportunities.
To make things more concrete: most local bulletin board systems and forum platforms are heavily tied to a specific commercial CMS. This is not a coincidence — government-affiliated projects often mandate that CMS, and developers here, lacking both English proficiency and exposure to global open-source alternatives, end up locked into its ecosystem. As a result, even basic AI censorship features become dependent on that vendor’s proprietary modules. When a tight deadline (less than a month) forces a purchase, there’s no room to explore better, cheaper, or more transparent options. The structure itself perpetuates vendor lock-in, weak technical capacity, and a cycle of superficial compliance rather than genuine innovation.
