How can it be said to show his opinion in 2006?

This is the only part of that post written in 2006:

"I can't find this on the web, so here follows a note I wrote in 1991 of an odd event in my computing career."

Everything after that is from 1991. You have no basis for interpreting the 2006 posting of this 1991 note as anything, save preservation of history.

True its strenuous, but its at least indicative in that he didn't distance himself from it in 2006 either.

You could imagine that if he felt differently in 2006 he'd have mentioned it in the preamble?

He posts one or two entries a year in that blog; this note was not some noise he dumped, it was a deliberate posting.

I can imagine a lot, but that doesn't mean I get to substitute my imagination for reality. You're reading into the post what you want, not what is there.

If you actually had any interest in truth, you'd ask him. Instead, you've decided you know what his views and motives are based on no evidence whatsoever, and are asserting your opinion publicly.

my bet, it's an opinion that helps google monetize on software research. whatever that is.
