Laudrup, who led the club to the League Cup last season, claimed on Tuesday he was dismissed by email because of a breach of contract - but has not been told what the breach was.
The club has yet to respond officially, but Monk feels it was a pointless move.
"He couldn't answer most of the questions for legal reasons," he said.
"So there was no real point in having it.
"If you call a press conference like that, you should be able to say what you want to say."
As well as leading the club to their first major domestic trophy, Laudrup also helped guide Swansea to ninth in the Premier League, their highest finish since they were sixth in the old First Division in 1982.
This term, he guided the Swans to a tie against Serie A side Napoli in the last 32 of the Europa League.
The first leg is to be played at the Liberty Stadium on Thursday.
But Swansea, who have placed club captain Monk in charge, won only three of 13 matches in all competitions before Laudrup was sacked on 4 February and there had been arguments over his coaching staff.
At the press conference on Tuesday, the former Real Madrid and Barcelona midfielder described the reasons given for his dismissal by the club as "silly" and "incredible".
He is pursuing legal action against the Swans over his sacking.
"It's not my problem," said Monk. "It's between the club and the chairman and the solicitors.
"It was strange as I have never seen a manager lose his job and then two weeks later have a press conference about it but if that's what you choose to do, you choose to do it.
"It's nothing to do with us [the team]. We have to move on."
