Watson along with pacers James Pattinson, Mitchell Johnson and batsman Usman Khawaja were dropped from the squad for "breaching protocol", according to the team management.
Jones treaded a cautious path while reacting to the news but the likes of Damien Fleming and Vaughan didn't stop short at taking a dig at the team management's decision.
"On a positive note Ed Cowan's presentation has just been nominated for a Nobel Peace Prize!" was Fleming's sarcastic comment, on his twitter page, @bowlologist.
"Before killing off Micky and Pup or the 4 Players alleged transgression, there are always 2 sides to every story. It will all come out," Jones tweeted.

"Not knowing the full facts. I wonder if Mickey Arthur rang James Sutherland CEO of CA for advice on this matter. Before sentencing.....If I was in Micky's shoes... I would have got advice from the CEO J Sutherland first. Then reacted."
But Jones also raised a question as to why the four Australian players didn't make the presentations.
Former England captain Vaughan made fun of the decision.
"What is going on with Aussie Cricket?? Didn't realise you had to do a Essay to get a selection these days..!!!!! Bowl better,Bat better, Catch better,communicate better... Just bloody play better.... I am now available for Selection of Australia..!!!!!," Vaughan tweeted, making a mockery of the Aussie team management's decision.
