"Did time suddenly rewind to 2007 again or something?" So you can't actually come up with a good defense for Peter making a literal deal with the Devil so you deflect. First of all, Marvel references much older stories and retcons them all the damn time (Hank Pym slap, Civil War, Phoenix, Wolverine's past, origin retcons). Second of all, it matters because it's damaging to Marvel's flagship character, you're lucky the media didn't notice, every non-fan I tell this to is horrified as well.
