There were obvious issues with telecommunication companies, but I believe this was largely due to reliance on external services like "Twip" and "Toonation" for sponsorship, a primary revenue model. In other words, there wasn't enough profit to cover expenses, so I think ending the service was a reasonable decision. For reference, I am Korean. My criticism stands as it is, and I don't wish to revise it. Public opinion here acknowledges that the internal structure is quite corrupt, but taking action is challenging due to a lack of broad, comprehensive information.
