It just feels like every social media site is login-walling public posts. I can't think of a major social media site (reddit, Instagram, FB, Twitter, etc) that doesn't do this to varying degrees. I can only think of minor sites (bluesky, truth social, etc) that allow access.

It feels like an end of an era.

Reddit is still viewable, though they did finally axe "old" reddit for those not logged in.

But at least reddit still has lots of nitter-style mirrors as an alternative.
