If I understand correctly, this doesn't take place in the main MCU timeline, it's its own separate universe. It's also not a simple What If-like scenario where there's one different thing, it's a completely different world with many Spider-Man characters actively doing stuff. It appears to only be slightly influenced by the MCU but otherwise has nothing to do with it and instead pulls from other sources like the comics, similar to older shows like Avengers Assemble. I don't understand why this wiki is covering it. I think it would make more sense to wait for it to come out and see if it has any noteworthy MCU connections like, idk, the Watcher introducing the universe in the first episode or something instead of fully covering everything before it even comes out, because right now I don't see anything that would really justify it
