Disagree with the theory. It doesn't have anything to do with Tony Stark because he's dead. Even if it did affect the past, Tony still met Spider-Man anyway.

The Integrated suit was damaged after the events of NWH. He either would've had to repair the old suit or make a new one anyway. He didn't have the tech to recreate a Stark-level suit, so he made it himself. It just shows he doesn't need all that technology anymore and his character's properly come full circle.

Perfect ending to a trilogy imo

Ends his current character arc really well.

The spell also influenced all digital stuff on the internet related to Peter, it's as Peter Parker never existed. He wanted to make a new start and he got inspired by Tobey and Andrew who made their suits themselves. But yeah, his suit doesn't know him, that theory has a great potention to be true, I like it! But I liked the Integrated Suit so much, but I also like the fact it's new begin for our hero...

I don't think Marvel has to make MCU Spider-Man 4 and ends the Marvel/Sony contract after NWH. While in cinemas two days back I realized this NWH ending is perfect for Spider-Man and they don't have to give him a new story but let it stay for what it is...

I think him making his suit was symbolic, the first three movies involved him relying in an older hero, iron man, mysterio, and dr strange, to guide him and show him how to be a hero. In all three movies he had suits made for him (or suit parts) by individuals he was looking to for guidance. I think him making his own suit was to show that he is ready to be his own hero, his own way

Also spiderfan2104, enough of this sony wanting out of marvel, its less realistic then the left twix vs right twix. Sony is purposely creating their spiderman related content with back doors into the MCU, they know the relationship is profitable, and they know fans wont be happy with them if they responsable for a third Spiderman series ending terably

I agree with the theory, that would make sense
