AFAIK the only evidence of tampered pages are those involved in this controversy. That archive.xx could tamper pages has always been possible (and a reason why Wikipedia should have their own archive, and migrate ASAP).

But still, Wikipedia can corroborate any archive.xx page, and if they find a matching source, archive that instead.

I don't understand the need to go "Hey the only bad things are these ones i already have."

That doesn't lessen anything
