The question they should be wondering about is - do they remember at least one instance where he did not walk and replays later showed him to be out. I can't ever recall Tendulkar getting lucky that way. Ever. He has been given out many times when he hadn't nicked. In 1997 tour of WI, Cumberbatch the chief among the long list of 'bongu' Windies umpires (and windies umpires are the most 'bongu' in the world) gave him out when the ball hit his shoulder and went to the keeper. And then we also had Umpire Rudy from South Africa rule Tendulkar out in South Africa to a dodgy Jonty Rhodes catch because - in Rudy's words - "Jonty is a true christian and won't lie"
I personally dislike walking. Strongly believe one should not walk. You are out only if the umpire gives you out. So didn't like Tendulkar walking. But this still had to be pointed out.
