Found: Spider-man Explains Civil War on YouTube
I'm looking for a specific fic that was probably on AO3.
The basic synopsis was that Peter Parker realized that nobody, not even the government, knew the actual story of what happened in the Avenger's Civil War, so there still hasn't been any resolution. I don't remember all of the middle, but Peter talks to MJ (and maybe Ned) who convinces him that he needs to do something because of justice or what Spider-man stands for, or something like that. Then Peter goes to Pepper and Tony and works with them to figure out how best to go about sharing the information. They consider PR and other things, I don't remember, and end up filming a video of Spider-man explaining not just the events of Civil War, but also what led up to it and why the different parties took the sides they did. The video also included footage from the suits and an image of the iron man armor after the Siberia fight. All this was uploaded to an untraceable YouTube account. The fic includes the public's reaction to the video, as well as Wakanda releasing a statement and Natasha anonymously contacting Peter to tell him good job.
The fic is definitely pro-team iron man, but there's not a lot of hate for the rogues that I can remember. The only characters that are actually bashed are Steve and Wanda, and even then it's not hateful, just distrusting.
