The AREXX error was my mistake. I just read the technology transfer part backwards when I was researching. I've already fixed it in the article and updated it.

The original tagline was "IBM doesn't make operating systems anymore for a reason" which could have been debunked by knowing anything about IBM's product line or about 5 seconds of Googling.

Disclaimer: I'm an Ars subscriber and <3 Ars but when my bullshit detector is already off the charts before the article begins ... it makes me wonder how good the article is.
