TechCrunch [techcrunch.com] posted July 5th that the login-to-view requirement has been dropped,
but:
The company hasn’t made any official announcement about allowing users to view links when you aren’t logged in or given any details on what measures it has taken to stop scraping.
Twitter’s move comes a day before Meta launches its own text-based app called Threads. Interestingly, Threads also briefly allowed users to view posts on the web without logging in before pulling the links. It is likely that people will be able to see Threads posts without an account when the app officially launches.
Others are noticing that Twitter previews can be viewed in
Slack,
iMessage and
WhatsApp.
