I can't speak for Vakanai, but I think you can make an argument that MCU Spider-Man doesn't feel like Spider-Man.
When you consider that Spider-Man was conceptualized as an empowerment metaphor for teens and for working-class people, a Spider-Man with ageist undertones who is reliant on the rich & powerful and blindly looks up to them would therefore be the equivalent of a Captain America who blindly looks up to the state. Forget my preferences as a fan, such a Spider-Man (like the MCU's) would be problematic for obvious reasons.
It is essentially a perversion of the values we've come to associate with Spider-Man, much like how John Walker/US Agent is a perversion of the values we've come to associate with Captain America. And that's not something that can be chalked up to it merely being an adaptational difference or creative difference; doing so borders on being a strawman argument.
