There is basically no way to parse that as "preserve" without the rest of the document stopping to make sense:

E.g

> judicial authorities are responsible for the supervision and control of websites in order to prevent the dissemination of criminal content

> other repositories with the same information have been created to prevent the content being withheld|preserve.

It is quite clear they meant withhold. The document just does not "click" anymore if you parse it as "preserve".

Also: No one in Spain would use "retener" to mean "preserve" as a synonym of "archive", anyway. "Retener" might loosely translate to preserve as in "to remain unchanged during a flow/process", but not in any of the other senses, and this is not the sense that is used here.

And, if there are was possibly any doubt left, Spain actually blocked the corresponding github.io subdomain (redirecting it to the usual "Your national FBI equivalent has blocked this domain for your protection" page) before sending this Github takedown notice (likely because they did not dare "withhold" the entirety of github.com itself).
