The point isn't to give Mr. Armstrong stick as an end in itself.
The thing is, Mr. Armstrong has questions to answer - look at the "Quiz" threads regarding his (now, apparently) non existent independent, imperative, transparent anti-doping programme. Look at the answers he gave about the programme before the announcement was made that he and Dr. Catlin were parting ways. Look at the way he equated Millar, Landis and Basso and seemed to say that fans cheering Millar without cheering Landis and Basso were hypocrites. Look at the way he seemed to threaten Pro-Cycling with no more access to him when he didn't like the (reader submitted) questions they asked him.
I do think Kimmage's cancer metaphor was out of order. That said, Mr. Armstrong sought out Don Caitlin because he was
