Musk announced a more expensive ad-free Twitter subscription

Twitter boss Elon Musk announced in a series of tweets Saturday that the company’s subscription service would show less advertising to users, including an ad-free tier.

The announcement comes as the social network has faced significant economic uncertainty since Musk’s October takeover. In addition, “there will be a higher priced subscription that allows zero ads,” Musk added. That would represent a significant shift in Twitter’s business model, which had previously relied on targeted advertising to generate revenue before launching a paid subscription service in mid-December. However, advertising has recently become a source of concern for Twitter, following Musk’s firing of roughly half of the company’s 7,500-person workforce late last year. The move raised concerns that the company was understaffed to handle content moderation and spook governments and advertisers.
