Why I Stopped Logging In to Read Tweets

Someone shares a tweet in a Slack channel. I click. Twitter shows me half the post, then drops a login wall. I close the tab. This happens constantly now. Public content — content that was publicly broadcast, on a public URL — has been quietly converted into gated content. Not by changing what's pu...
