Elon Musk said Twitter might soon charge fees for certain users, as the billionaire continues to tease how he might change the platform as its new owner. Musk, who struck a roughly $44 billion deal to buy Twitter, said in a tweet the platform will “always be free for casual users,” but there might be a “slight cost for commercial/government users.” CNN reports that Musk’s suggestion that Twitter could start charging some business and government users comes as company staffers and millions of Twitter users await any clues for how the takeover will impact the platform he’s now seeking to take private.
