More than three years ago, Twitter prohibited political and issue-based ads amid broader concerns that politicians could pay to target social media users with false or misleading information.
Now, under its new owner Elon Musk, the company is easing that ban, in a move that could provide Twitter a much-needed sales boost at a time when Musk is urgently searching for new revenue streams. But it comes with some risks: the policy change could expose users to threats the company has previously said it may not be able to address, including spreading AI-created deep fakes and other sophisticated attempts to manipulate the platform.
