If Rhodey staged an intervention after Ultron, it would NOT be to prop Tony
The story that inspired this checks off quite a number of prop-Tony tropes:
1. Natasha's info dump caused multiple deaths (because apparently Shield not only hacked into other government agency servers, Shield also copied and pasted all the files into their own databases. Why? To bash Natasha, of course). And apparently PTSD in Shield agents interrogated by Hydra. (Which makes zero sense, because Hydra already knew all of Shield's secrets from the inside.)
2. Other heroes line right up to sign away their civil rights and join Team Iron Man (even Magneto, I believe).
3. Amending the Accords is super-easy because Tony, even though Infinity War showed that Tony was lying about being able to make amendments.
4. Team Cap somehow fail to read a newspaper or see a newsfeed the whole time this is going on. (Why? To bash Team Cap, of course.)
But the saddest thing about that story is what it does to Rhodey. Rhodey saw first-hand the damage that Tony's recklessness caused: Rhodey saw what Ultron did to Sokovia after Tony unleashed his flawed program onto the Internet using Loki's scepter. Yet this story has Rhodey staging an intervention to prop Tony and bash the Avengers. The ones forced to clean up TONY'S mess. And prop-Tony people claim SAM doesn't think for himself...
Let's see how Rhodey would REALLY react in this absurd scenario.
***
Rhodey wandered around the lab where Tony had decided he knew better than anyone what the world needed. Rhodey had reviewed all the footage. Tony bullying Bruce into unleashing Ultron. The recordings of Ultron's ravings as he quoted Tony and planned genocide, showing pretty clearly just how flawed Tony's program was.
He shuddered to think how close the world had come to Armageddon. Sokovia would never be the same.
Rhodey turned when Tony walked in. He pointed to a chair and ordered, "Sit."
"Do I get a biscuit if I give you my paw?" Tony asked as he sprawled in the seat. Clearly he wasn't all that broken up about his part in the destruction of the last few days.
What you're going to get is some truth, so listen up," Rhodey said as he stopped in front of Tony's chair. He continued, "What the HELL were you thinking? Your little stunt unleashed a murderbot that destroyed AN ENTIRE CITY."
"You don't get it," Tony snapped as he stood up and pushed past Rhodey. Tony continued, "Ultron was supposed to save everyone. So we wouldn't need the Avengers."
Rhodey shook his head and asked, "So why didn't you get a second opinion on this genius plan? Like maybe from Thor, who actually KNOWS ABOUT THIS SHIT."
Tony shrugged and said, "Thunderdome would have never let me play with his little brother's joystick. And Captain Stick Up His Ass would NEVER have gone for it."
Rhodey leaned against a table and said, "You don't get to go off and invent a deathbot behind their backs because you don't want to hear someone tell you No. The Avengers are a TEAM, Tony. It should have been a TEAM decision."
Rhodey crossed his arms and said, "Instead, you showed yet AGAIN how genius is just another word for stupid. And the rest of us got stuck cleaning up YOUR mess."
Tony lifted his arms and said, "So what are you going to do? No pudding for a month? Scrub the toilets with my toothbrush?"
Rhodey frowned and said, "Even now, you're not taking it seriously. I volunteered to tell you, Tony: You don't get to sweep this under the rug and walk away. If you want to pretend you're a naughty child, then here you go: We're taking away ALL your toys. And you don't get to build any more. You'll be restricted from ANY technology involving robots, AIs, weapons, or the Internet."
Tony laughed and said, "Right. What are you all going to do without me? I'm the brains of this operation."
Rhodey snorted and said, "Sure you are. But just so you know, we're going to be recruiting some more heroes and more tech help. And making sure THEY understand that just because they THINK they know better than anybody else, that doesn't make it true. And we'll be pointing to YOU as the example of what NEVER to do."
The other Avengers filed into the room, followed by two officers. Tony frowned as Rhodey frisked him and got EVERY piece of tech Tony was hiding.
As the officers slapped handcuffs on him, Tony looked over and saw Rhodey being comforted by Steve and the others.
They looked like a real team.
