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.
Am I remembering correctly that when Elon first took over, he took that gate down because of his whole free speech thing. I'm guessing they re-instated it as soon as it hit the bottom line. Makes me wonder if government should still rely on it for comms.
One of the first things Twitter did post Elon was remove sign in gating then I guess the bankers pressed Elon and it went back up. Can't always do everything you want in business, I guess. Bills come first.
Yep, Twitter has had aggressive authentication gating for almost 2yrs now and HN frequently has Twitter links
