Tony screwed up the FBI operation in Homecoming
This is an interesting theory that says Homecoming shows Tony has no sense of strategy. In this take, it was stupid for Tony not to accompany the FBI when they were going against Chitauri weapons. And Tony didn't even consider what would happen when the authorities asked him why he had so many dangerous weapons flying in an unsecured plane.

Tony tried his patented charm on the red-hot agent interviewing him.
It didn't work. She stared back with a blank expression and said, "Mr. Stark, please focus. There are still a lot of questions to answer."
She looked at her tablet and said, "Next question: Why did you not warn your FBI liaison of the dangerous nature of the Chitauri-derived weapons?"
The agent looked up and said, "Nothing in the FBI arsenal could match or protect against the firepower of a hybrid Earth-Chitauri weapon. It would seem a 'genius' such as yourself would have lodged a protest against the decision to send in a standard FBI team to deal with the threat."
Tony frowned. The truth was he wanted to teach the FBI a lesson in Iron Man appreciation. He didn't think Lady Agent would approve. He said, "I didn't think about it. I was told to stand down so I did. Until I was called in."
The agent frowned and typed something on the tablet. Friday couldn't hack it, which was NOT good.
Lady Agent said, "Now to the matter of the airplane attacked by Toomes and his team. Is it correct that it was unmanned and had no guards on board?"
Tony shifted in his seat and replied, "Yes, but..."
When the agent didn't interrupt him, Tony blinked and cleared his throat. He said, "But, uh, I can't trust ANYONE. So of course I used technology rather than people."
The agent lifted an eyebrow and asked, "So you do not trust War Machine and the Vision?"
Tony looked away and drummed his fingers on the table. He said, "So, uh, Vision isn't exactly following orders these days. And Rhodey..." Rhodey would have likely called Tony's plan stupid, so of course Tony didn't tell him about it.
He finished, "I didn't think to include them."
The agent typed something else. The she asked, "Why didn't you provide ANY security measures on this unmanned plane?"
She leaned forward and said, "Even if Iron Man himself couldn't be on board to make sure this extremely dangerous and sensitive material safely reached its destination, why didn't you leave a suit on sentry mode on the plane?"
Tony's eyes narrowed and said, "How do you know about that?"
The agent asked, "Why does that matter? The question is, why didn't you bother to secure the transport?"
Tony said, "No one was supposed to know about it. How could I have known it would be hijacked?"
Lady Agent shook her head and typed something. Then she closed down the tablet and stood. She said, "Mr. Stark, I will be filing my report with recommendations that your arsenal of alien technology, weaponry, and other materials be throughly evaluated and confiscated as necessary for the safety of the planet. Be aware that this compound is being monitored, so I'd advise against trying to hide any of its contents."
She turned on her heel and strode out without even a good-bye.
Tony muttered, "Bitch."
