I looked them up on Wikipedia. Good catch! Typo. And if I were consistent, I would have made a note on the restructuring as I did in a couple of other cases. The commenter apologizes for the error. ;)

I also checked Berkshire Hathaway (1889). It actually goes back to 1839. But does a series of mergers and acquisitions actually count here? The modern form came from Warren Buffett buying shares in it in 1962, and eventually buying them out years later. Buffett's version of the company has pretty much no resemblance to the company he bought out, they aren't at all in the same business, and he mentioned in 2010 that BH was more of a hindrance than a help.

Notably absent from the list are behemoths of the past, like RCA, Kodak, Sears, IBM, Ford, GM, US Steel, Union Pacific, etc.

My point (which I'll repeat once and then I'm done) is not that established companies never get disrupted or innovate forever, but to push back against the idea that established companies can't innovate (and that The Innovator's Dilemma contends that disruption is the only way innovation happens), which I took from "Innovation doesn't come from established corporations." (https://news.ycombinator.com/item?id=16665304) I don't see anything you've added that contradicts that.
