I have read a few accounts that said it was his vindictiveness against those who wouldn't " toe the line " , even when they moved to the periphery of the sport.
I saw a documentary about it all a few years ago
It was done by a female journalist who was not around at the time (too young) and thought she might have an outside view after all the time gone by
She deliberately decided to refuse to talk to him or "his people"
it was very well done - with commentaries from her on how ti was going as it went along
Over lahf way through she did a "face to camera" thing again
this time she said that Lance had heard that she was doing it and asking if he could help (or whatever)
but she had had people say "One Lance is involved - all you will get is the view Lance wants you to have"
which is why she had avoided talking to him in any way up to that point
But she had talked to everyone that was involved and "not in Lance's camp" so felt she needed to look at the other side
so she had accepted an invitation to talk to him
BUT - she had decided to pretty much finish up the first 2/3 of the documentary and then NOT change it again
THEN talk to him and do the rest of it
so we could see the impression she had at that point fixed and not modified after
Then she interviewed Lance
WHo was wonderful and charming and very "honest" and admitted a lot fo the things that everyone knows about
but showed all the things he was doing to help people
The things about it all was that the "once you talk to Lance all you will get is what Lance wants you to get" reall came out
even though she talked to people who disapproved afetr that - there was an atmosphere of it being controlled by Lance afetr that
the views were often "Lance did Bad" like before
and the stuff before was never allowed to be "Lance is the Devil" type stuff - just accurate and detailed
but the difference was there
which, of course, might have been deliberate
or validated the "don;t talk to Lance if you want the truth" camp
dunno - but it was interesting
