By that logic, what are firefighters doing but censoring homes? What are koalas but a form of eucalyptus censorship? What is locking your front door but a form of censoring burglars?
No, just no. Censorship is preventing the transmission of ideas, nothing more, nothing less.
Deleting a file has nothing to do with transmission, and it's being done in response to a perceived threat, not its communicative meaning. (Like how you lock your house to protect from burglars.)
It's important not to abuse the term "censorship" -- if it means everything then it ceases to mean anything at all.
