Online journalism is a joke.
Most articles are straight up copied from other sites, which copied them from another site, which copied them from the original source, which got some information from another person, which was in contact with Ming-Chi Kuo.
There is a lot of potential for errors, only one journalist has to interpretate something wrong and it will get copied by others.
