Elon Musk is encouraging car manufacturers to resume advertisements on Twitter after his purchase of the social media giant.

From the moment the world’s richest person acquired Twitter, a number of the world’s largest carmakers paused advertisements on the platform, including Volkswagen, Stellantis, and General Motors. Musk wants them back.

While speaking in a town hall for advertisers broadcast on Twitter Spaces earlier this week, Musk pledged not to give unfair advantages to Tesla and said that he hopes other auto executives will become more active on the platform.

“We will try to be as fair as possible”, Musk said.

General Motors was the first major automaker to suspend advertising on Twitter following Musk’s acquisition.

“We are engaging with Twitter to understand the direction of the platform under their new ownership,” General Motors said at the time. “As is normal course of business with a significant change in a media platform, we have temporarily paused our paid advertising. Our customer care interactions on Twitter will continue.”

Soon after General Motors paused advertising, Stellantis followed suit, suspending advertising for all of its brands, including the likes of Dodge, Ram, Jeep, Fiat, Peugeot, and Alfa Romeo.

Musk has already admitted that Twitter’s revenue has suffered a massive decline since he took over on October 27. He has also acknowledged that the $44 billion he paid for the company far exceeded the company’s net worth. Had he not had an impending trial to worry about after previously pulling out of a legal-binding agreement to purchase the social media company, Musk might not have followed through with the acquisition.
