alt Hacker NewsHN often has twitter links when this is the primary source; in that case in comments there are usually links to mirrors or threadreader.
Here twitter is not the main source, there are better ones (both better quality and more user friendly).
I would like a rule to avoid submissions that are login walled unless this is the primary source and an open mirror is available.
I've been on HN since the very beginning and the solution has always been simple: if the post is auth/pay-walled then post archive links or copy paste the text in comments.
I get why there's noise about banning X suddenly but lets not pretend it's for sudden technical/UX concerns. No one is calling for NYT, WSJ, or WaPo submissions to be avoided. Twitter had auth gating for many years before Elon.
