Tony and Kang are a lot alike
This is really interesting. The theory is that because Tony was okay with stripping people of their "precious freedoms" so he could have his vision of security, he was basically agreeing with Kang, who was okay with taking away people's free will to protect the "sacred timeline."
Note: In his series Loki thought he smelled the stench of Tony's aftershave. I'm not sure how the TVA works.

Tony tugged at the collar around his neck as he was dragged through bland corridors of this weird place. He asked, "Don't you know who I am? Just where are you taking me?"
One of the goons shrugged and said, "Tony Stark aka Iron Man. To see the boss."
Tony nodded. FINALLY he'd get some answers.
The doors opened to an imposing figure seated on a throne-like chair. The man leaned back and said, "Ah, Mr. Stark. You're just in time."
As he was released by the goons, Tony asked, "In time for what?"
The man said, "To join my service."
He stood, stepped over to Tony, and said, "I am Kang, but you may address me as Sir if you ever report to me again."
Tony crossed his arms and said, "You aren't the boss of me. I don't HAVE a boss."
Kang smiled and said, "You do now. If you wish to keep living."
Tony felt a pulse from the collar. When he lifted his hands to touch it, he got a shock that dropped him to his knees.
Kang said, "You don't want to mess with that. The results could be...explosive."
At Kang's signal, a goon stepped forward and lifted Tony to his feet.
Kang said, "We have a lot in common. I believe that you will come to see the importance of our work here."
Kang briefly explained about the sacred timeline and the TVA's purpose in preserving it by pruning rogue variants.
Tony said, "What the hell? Why would you think I'd help you destroy universes?"
Kang lifted an eyebrow and said, "Am I not speaking to Tony Stark, Merchant of Death? The man who made weapons of ever greater destruction for decades? Who used alien technology to upload his own personal global security system, and followed that up with a drone version of the same thing? Who insisted that the Snap NOT be reversed, forcing the trauma and loss of trillions across the universe to remain?"
Kang seemed to be waiting for an answer. Tony finally admitted, "Yeah, but--"
Kang interrupted to say, "But that was YOUR vision you were manifesting. Yes, I know. But it's the same principle--all others are denied their right to choose so you could choose for them. And you did."
Kang smiled and said, "So do I. And I am now choosing for YOU."
Some part of Tony finally realized just how wrong he'd been to try to force his will on people against THEIR will. Too bad he learned his lesson too late.
