This is definitely interesting and HN-worthy. If nothing else, archive.today links are posted on tons of HN submissions, so it's topical.

I agree - it's clear that archive.is / archive.ph / archive.today / who-knows-what-else has been a lubricant in many HN threads, letting people read things they otherwise couldn't, and that increases the interest of the topic.

I suppose I should add that we prefer archive.org links when they're available, but often they aren't.

Edit: I suppose I should also re-add that we have no knowledge of or opinion about what's going on in the dispute at hand.
