No one was complaining; they were mentioning that fans can create content. And as platforms to share content proliferate and the means of production become more democratic - an iPhone can now take the place of a heavy duty film camera and an editing bay and a distribution service all in one - I sincerely believe we'll start to see some fan content become even more popular than "official" content. That's the takeaway conclusion.
By the way, the fan content can use the Spider-Man name. Disney isn't going to come after them, unless the fan content reaches the stature of the
Unofficial Bridgerton Musical and even then, Netflix didn't sue when the creators won a Grammy, they didn't sue when the creators were getting nationwide publicity, they only sued when the musical was booked into Lincoln Center and even then Netflix offered the creators a license so the musical could continue but the creators said no.
Disney didn't even mention Marvel Comics on their earnings call to investors today. The only reference to Marvel was in creating more original MCU material to prop up Disney+ subscriptions. That's how important Marvel Comics is to the parent company.
Also, as someone who is a creative writer teacher, I am surprised you appear to be preaching that imagination has limits.
