April 1 2013
Wikipedia says:
> The company initially planned to change its name to "Exon", in keeping with the four-letter format of Enco and Esso. However, during the planning process, it was noted that James Exon was the governor of Nebraska. Renaming the company after a sitting governor seemed ill-advised, and the second "x" was added to the new name and logo.
No mention of them wanting to name the company with a greek chi but not having that on their typewriters.
To be fair, the wikipedia claim isn't cited. Neither is rms's of course.
...although looking at it more carefully, the doxing article is not dated April 1, and it has the same claim in it. Maybe he forgot what he was doing and successfully trolled himself. I don't know. But yes, the Exxon thing is obviously, demonstrably false.
