I would wager money on the suspicion that deep down, Linus probably still thinks he did nothing wrong.

And that the actual change only came about because the people around him (like his wife and executives) threatened/forced him into changing positions.

Cause we got a good glimpse into the kind of person Linus was when that whole thing started, by selling the prototype that wasnt his, then going out and lying about being in contact with the company, who he lied about forgiving him and making a deal to make up for it... Which was quickly rebuked by GN asking the company if Linus had contacted them, to which they said "No"

And the kind of guy that does that kind of shit, isnt the kind of guy that suddenly goes "Okay, I screwed Up, I did it, I'm sorry" without someone behind the scenes threatening catastrophic personal consequences.
