Pretty much. While I wouldn’t say that I’m obsessed, I would greatly appreciate it if usage increased. I wish open source software was the norm.

This is very common (compared to the rest of the population) amongst Linux users. Some people therefore feel the need to spread awareness.

I don’t think it’s big enough to have a noticeable impact. It’s estimated to be between 5000 and 50,000 people strong. South Korea had an estimated population of 51,430,018 in 2023. That would make between 0.0097% and 0.097% of their population a part of 4B. So a tiny fraction of the population might have gone from a fertility rate of 0.72 to 0. That’s between 3600 and 36,000 fewer kids.

When I tried to find out how many people were a part of the movement several sources had old estimates because the movement has supposedly almost died out in South Korea. So it might be even less that 3600.

I worked in one of the biggest telecom companies in Europe. This is most likely an order made through customer service. The telecom companies have known about this problem for a long time. They are trying balance security and ease of use for the customer.

If company A implements noticeably stricter requirements for identification to order stuff, the average customer gets annoyed and switches to company B.

Therefore the companies watch each other closely and implement stricter requirements slowly at about the same rate as their competitors.

Protip: You can contact customer service of most telecom companies and ask them to write down a password that you need to tell them before you can order a SIM or other stuff.
