Ask HN: Why is HN replacing Twitter URLs with canonical URLs requiring login

Earlier today I submitted a URL from twitter.com because it was the URL for the content that I wanted to share. That URL was rewritten in the form:

https://twitter.com/i/flow/login?redirect_after_login....

This causes fellow users to have to login to X / Twitter to have to view the content/tweet.

Why is this happening?

For me this is functionally equal to blocking twitter links.

Does the tweet have a canonical tag in the HTML? Asking because HN will redirect to the canonical name. That's why I use an addon to show me if that exists to save me some hassle when I submit URL's here. HN seems to ignore canonical for some domains like Youtube video URL's. Perhaps that exclusion list needs an update but probably best to email dang to ask.

Because twitter is broken. This is surely not news, a year in. You may want to submit a nitter link instead.
