Former captain Michael Clarke said it was "devastating" to watch, while another fan said it was "awful".
Cameron Bancroft was also praised earlier for acknowledging his role in the saga. Former deputy prime minister Barnaby Joyce, who recently endured his own national scandal that put him at the centre of a media storm, tweeted "enough is enough" for the young players.
"Smith, Warner & Bancroft did wrong, they have paid for it. What are you trying to do? They aren't criminals," (sic) he said.
Other high profile fans including Leigh Sales and Andy Lee weighed in to say the apology was the "best way to start the road to redemption."
However former England captain Michael Vaughan took aim at David Warner for refusing to front up in person, saying: "2 out of the 3 players fronting up to the media. Speaking honestly and in great regret. 1 speaking through a statement on social media!!!" (sic).
News Corp columnist and Sky News commentator Andrew Bolt said the reaction was "so savage" he wondered if the nation had "collectively gone way over the top".
Former Australian cricketer Gavin Robertson agreed that the sanctions exceeded what many expected but said the players might each make a return to the game.
"I think we're a very forgiving country ... I just think there is so much more to play out in this story," he said.
It comes after Cameron Bancroft fronted the media in an emotional press conference.
"I love the game of cricket and playing for my nation and my state. There's no greater pride for me," he said.
"I'm extremely disappointed and regret my actions, I'm sorry to those people who have looked up to me in the cricket world and especially the kids."
"I know I'm a role model but haven't acted like one in this instance. I understand I have let many people down and I understand the disappointment in the community.
"Not a second has gone by since last Saturday evening where I haven't wished to turn back time and do the right thing during the lunch break.
"It's something I'll look to improve on and earn the respect back of the community.
"All I can do in the short term is ask for forgiveness and hope you can find it in your hearts to let me progress on that journey.
Meanwhile David Warner released a statement on Twitter.
The 31-year-old dumped vice-captain confirmed he will land back in Australia on Thursday night and acknowledged his role in the plot.
"To cricket fans in Australia and all over the world: I am currently on my way back to Sydney," Warner wrote.
"Mistakes have been made which have damaged cricket. I apologise for my part and take responsibility for it.
"I understand the distress this has caused the sport and its fans.
"It's a stain on the game we all love and have loved since I was a boy.
"I need to take a deep breath and spend time with my family, friends and trusted advisers. You will hear from me in a few days."
