It's not related. This is a world where the Squadron Supreme are the main superheroes. Everyone else either has no powers or has their backstory DC-ified. For example, Peter Parker isn't Spider-Man, he's Hyperion's Pal, the Amazing Shutterbug... i.e. a newspaper photographer like Jimmy Olsen (and like Peter was originally when he first became Spidey). Kamala Khan isn't Ms. Marvel, because Carol never unlocked her powers. Instead, she's Power Princess's sidekick Girl Power, an expy of Wonder Girl Cassie Sandsmark. The Champions still exist, but they're called Young Squadron. Miles and Sam have different identities as well, Falcon (Nighthawk's sidekick i.e. Robin) and Kid Spectrum (Doctor Spectrum's sidekick i.e. Teen Lantern). In the case of Siege Society, you can see that Clint Barton, Natasha Romanoff and Scott Lang all never became heroes because Iron Man (and in Scott's case, Hank Pym as well) wasn't around for them.
