The sub headline is kinda important here:

Seoul wants to direct use of homegrown AI chatbots to reduce reliance on U.S. or Chinese options, footing the bill and offering unlimited tokens

Also, it only seems to be access to special purpose chatbots, not e.g. unlimited API access for use with your own tools.

Dude are that many people actually subscribed to the WSJ? or do they just read the headline and post the link
