Both parties said on Tuesday they had "mutually agreed" for Ronaldo to leave the club with immediate effect.
Last summer the Portugal forward, 37, told United he wanted to leave and he criticised the club in a controversial interview last week.
"I think both parties have got what they wanted," Ferdinand told the BBC.
"When he mentioned in August he was going to reveal some of the details behind the scenes, this was almost like a ticking timebomb.
"I think he felt he was pushed into a corner, in his own mind, and he did what he did [the interview] to get this outcome.
"He put the club in a position where it was an untenable situation. Was it handled perfectly? I think, from both parties, no. But if you look at the end game, they've got to where he and the club, through the manager's eyes, wanted to get to."
United announced in April that Erik ten Hag would become Ole Gunnar Solskjaer's permanent successor in the summer.
He arrived at Old Trafford with the reputation of being a disciplinarian and it was unclear how Ronaldo would fit into his tactics once the club had decided not to sell the player.
The Dutchman has had to discipline Ronaldo this season but the Portuguese was captain for what proved to be his final game for the club, a defeat at Aston Villa.
And Ronaldo said in his interview with Piers Morgan for TalkTV that he does not respect Ten Hag.
"In the end, everybody loses, except the Manchester United manager," former Manchester City and Belgium defender Vincent Kompany said during the BBC's World Cup overage.
"It's a problem that's resolved, they'll move on from this."
Ex-England captain Alan Shearer added: "It's a sad end to his Manchester United career. It was never going to be a match, Ten Hag and him.
"It will be really interesting to see if a Champions League club comes in for him."
Former United team-mate Wayne Rooney, whom Ronaldo criticised in the interview, told Indian broadcaster Viacom18 Sports: "It's a shame because he's been a fantastic servant for United.
"I'm sure there'll be teams looking to sign him. Certainly, if he has a good [World Cup] tournament, there'll be a lot of teams looking to try and sign him."
Many feel the final outcome could have been avoided. Equally, many felt once Ronaldo refused to come on against Tottenham, he would never play for the club again.
Instead the additional couple of weeks just brought festering discontentment to a head.
Given his status, Ronaldo felt he was entitled to get his point across. He knows what it takes to win and saw a club that is miles off.
It will now be fascinating to see if Ronaldo remains in the Premier League.
As for United, they have invested a lot in Ten Hag. They believe the Dutchman has them on the right path. Time will tell whether they are right.
