Any good archiver will check for an archived copy before making a request, and batch requests. This was very different than the attack you’re imagining — if you opened any archive.today page, it would poll a developer’s personal blog, regardless of whether you were interacting with content from that blog.
I’m certain they’ve wanted to do this for a long time, and AI is a convenient way to justify it, rather than admitting they don’t want humans using it to circumvent the paywall. It does solidify for me personally that the LA Times is the paper of record for the United States going forward, rather than the New York Times.
