This whole debating thing is new to you, huh? Let me explain it to you like you are a 4th grader:
(1) This is really simple. Rider (B) says that Rider (A) should stop talking and thank his team mates, and implies that Rider (A) suggests that he won because of his own efforts because he hasn't publicly thanked the team. Now Rider (B) has finished, let's say 3rd, after a tremendous amount of work on the part of the team (specifically Rider (K) who sacrificed his podium aspirations for Rider (B)). Rider (B) has not publicly thanked the team in any of his statements or his twitter account, which according to the standard HE IS ADVOCATING SHOULD BE APPLIED TO RIDER (A) means that he hasn't thanked his team mates for their effort. As such, Rider (B) is a hypocrite for advocating a standard that he hasn't lived up to. Or in more cliche terms, he is not practicising what he preaches.
(2) We now have sufficient circumstantial evidence to suggest that Rider (B) is either (I) not telling the truth or (II) is demonstrating that his absence from the team dinner on Saturday and general lack of a relationship with Rider (A) means that he has an insufficient basis to draw conclusions about what actions Rider (A) may or may not have taken.
That's as far as I've gone. Not hating on Lance. Not loving on Alberto. Just pointing out the inconsistency between what Lance is advocating and what Lance is actually doing. Both achieved success with the assistance of the team, with one receiving more than the other. Isn't it odd to argue that only one of them owes their team mates a public thank you? And yet, here you are doing precisely that.
And I just wrote all of that without actually shifting in my chair once.
