But those are rumours that aren't making any sense. If he was against interconnection then why were Kevin Feige and Joss Whedon supporting his stance on the matter? We're talking about the man who came up with the idea for the shared universe (and who is responsible for the production of every single movie to date from Marvel) and the man responsible for overseeing the interconnection now (who also directed their most successful film).

Another idea around that makes far more sense is that somebody in Marvel proper or Disney tried to change the script to make it feel more like a "summer blockbuster" and make more money as a result, therefore everyone behind the MCU fell out with them over it and Edgar Wright has walked (certainly the plan is to have a sequel and a new property every year with the idea seemingly being the "sequel" makes a lot of money, and the new property is for the more creative, artistic, fan-pleasing and frankly riskier elements because the big blockbuster sequel can cushion a potential flop).
