I actually have tried to get published some places, but got rejects. I have also added a lot of stuff to the tvtropes Spider-Man page. I am especially proud of summarizing in chronology every single Spider-Man run and event in 616.

I also added a collection of quotes to represent Spider-Man there:

Stan Lee gets multiple entries but I have gone one for each for every major writer.
That's generally the case across the board for both DC and Marvel. There's also hierarchy in that flagship characters (Superman, Batman, Spider-Man) are more protected than those that are obscure. So you can do more stuff to the latter. For instance you can't show Reed Richards be a self-destructive abusive husband that subtextually he comes across a lot in the Lee-Kirby era, but you can do it textually with Hank Pym because Hank isn't a major hero and a protected character like Reed is.
Jim Shooter forbade Bill Mantlo from making Felicia Hardy the mother of Spider-Man's illegitimate child citing the number of contracts with morality clauses Marvel signed with kid friendly products to license Spider-Man, and Quesada nixed Peter father Gwen's kids in JMS' run. On the other hand, Jessica Jones and Luke Cage could have a baby before marriage because Luke Cage was a minor character and Jessica was introduced in a MAX Series.
Spider-Man fundamentally exists in a very sanitized corner of Marvel. By the nature of his genre. So his stories don't deal with rape, prostitution, or even stuff like strip clubs (see ASM Wedding Annual #21 where Peter, Harry and Flash's bachelor's party is hanging in a college dive and going on about how old they've become...which is more or less what strip club visits amount to). In the Marvel Shared Universe, Peter exists with Jessica Jones, Punisher, Daredevil and their stories touch on all this but not Spider-Man. The reason is well you can't sell Peter whining about "parker luck" when in a story he comes across a rape victim or people who have actual misfortune and suffering.
That also limits stuff you can do with Spider-Man politically and socially. So Peter's supporting cast, a la Star Trek where Kirk has to decide between Spock and Scotty also navigates his supporting cast in different ways and to similar effect.
Isn't Dr. Sun Yat Sen one of the revered founders of China a guy who insisted on freedom of speech? I don't think confucianism or any such thing is justification for totalitarianism. After all freedom of speech wasn't something inherent to Western society, I seem to recall society being made to accept it after much blood and tears.
