Prior to this, there were rumors circulating from Fortune that X would no longer display headlines when posting links from external platforms. Only a featured image, article summary, and domain linked to the external content would be shown. However, X has now updated and completely removed external web headlines on the iOS system. This change was initiated by Elon Musk himself, as he wanted to enhance the overall appearance of the platform.
TLDR: X, under the guidance of Elon Musk, has eliminated external web headlines on the iOS system to enhance aesthetics. Musk encourages users to post directly on X, as links tend to decrease engagement. Lengthy content is preferred on the platform. This update reflects a focus on maximizing user experience and promoting user-generated content. Source: The Verge.
