Meta Platforms Inc's app, Threads, is facing criticism for blocking standard search terms, limiting its usefulness. This has raised concerns about Threads' ability to provide real-time information and cater to diverse discussions. The lack of diverse content could impact Threads' potential advertising business. Threads' daily active users have plummeted to below 10 million from over 100 million. The average duration on Threads also dropped from nearly 21 minutes to 3 minutes within a month.
