"At the end of our games, it was pure box office," said former Swindon chairman Jeremy Wray. "It is a great appointment for him and a fantastic appointment for Sunderland."
Di Canio clashes with his own player
Sunderland, who have seven Premier League games remaining this season, are just one point above the relegation zone. They have tough trips to Chelsea and Tottenham, as well as a north-east derby with Newcastle to come.
But Wray believes the Italian can keep the Black Cats in the Premier League.
"He will galvanise the team," Wray told BBC Radio 5 live. "He is full on 24 hours a day and will be focused on the last seven games of the season. If you are looking for a catalyst for change, he is absolutely the right man."
Di Canio first came to Britain as a player in 1996, when he joined Celtic, and followed his time in Glasgow with spells at Sheffield Wednesday, West Ham and Charlton.
He retired in 2008 after spells in Italy with Lazio and former Serie C1 side Cisco Roma.
"It is a sad, knee-jerk response," said Wray. "I doubt David Miliband knows Paolo. I knew him for two years, but we never spoke about politics.
"It is not relevant to keeping Sunderland in the Premier League."
However, Football Against Racism in Europe director Piara Powar insists it is important for Di Canio to declare the nature of his political beliefs.
"When there is a rise of intolerance and there is a coach in the most watched league globally, who hasn't clarified or wanted to renounce his fascist views during his time in the UK, it is a worrying time," Powar said.
"We live in a different political climate than 2011 and there has been a lot gone on in football over issues of race and that gives a different focus to a manager who calls himself a fascist being appointed to a top post.
"Fascism is an ideology which at heart is about intolerance and a way of government that has no place in the 21st century.
"There are all these good footballing reasons to employ him, but are footballing reasons enough when someone comes with the baggage he comes with?"
