Can somebody with development knowledge explain to me this?

I first heard of this show around two or 3 years ago at this point. And I’m CERTAIN the initial announcements were that it was supposed to be a prequel show, set in the MCU, basically showing Peter as Spider-Man before Tony found him and civil war happened.

So presumably him in his shitty home made suits, more original explanations, more minor villains since he shouldn’t be handling crazy city threatening events yet

Did plans change? Or did they not announce it was set in the MCU and this was misinterpreted somewhere?
