You're comparing apples and oranges here. In the Tylenol case, it seemed clear that the cause wasn't neglicance on the part of J&J, and the remedy of clearing all product off the shelves probably cost them somewhere in the millions of dollars. In Boeing's case, the issue almost certainly is due to intentional actions taken by a number of people, and buying back existing 737 MAX8s + cancelling all future orders would amount to billions and could very well sink the company. I think the parent comment is spot-on. Boeing is playing a game of damage control, and they're presumably being advised by some smart and experienced people. They're not accepting blame, an act which we can assume is motivated by the legal implications of doing so.
