Sony literally cannot stop making spiderman movies. Part of the deal when they bought the rights from Disney in 1998 was they have to make at least one spiderman movie every 5.75 years, or the rights are forfeit. https://www.octalcomics.com/when-does-sonys-spiderman-rights...
Innocent mistake on OPs part I assume. Marvel sold the rights of X-men and Fantastic Four to Fox and Spider-Man to Sony. Paramount made a big mistake not doing anything except being the distributor for set periods of time.
