To be fair, your argument has been made by others on the RfC too, comparing the situation with Wikipedia linking to Anna's Archive.
Truth is, when being honest, Wikipedia should never have started linking there. It probably started out of noble intentions: making sure sources stay available for everyone.
Now a new factor has come into play - that the site is being weaponized. The admin there has surely the ability to modify whatever he wants, create fake articles, change the wording of others and so on, and has now proven - without a single doubt - that he is not trustworthy.
This means that the reliability of all hosted information has to be questioned as well. And here we are.
