The HN rule is that anything can be posted if it is accessible to everyone, including via a paywall workaround if it has a paywall that is porous.
The community has converged on this being the least-worst approach after wrestling with the issue for well over a decade, and it's sufficient to helpfully post the archive link without a snarky editorial comment :)
i found out that most articles behind paywalls dont even need the wayback machine to be viewed
if you are using firefox, just enter reading mode and you can read the entire article without popups in your preferred background, text color, font, etc
