Did AT go beyond that and manipulate any relevant part? That's rather difficult to say now. AT is obviously tampering with evidence, but so is Wikipedia; their admins have heavily redacted their archived Talk pages out of fear one of these pseudonyms might be an actual person, so even what exactly WP accuses AT of is not exactly clear.
Unless you're arguing that the response by archive.today retroactively justifies the behaviour of Jani Patokallio, which would be a bizarre take.
