Elon Musk became Twitter's new owner on Thursday, firing top executives he had accused of misleading him and providing little clarity over how he will achieve the lofty ambitions he has outlined for the influential social media platform.

The CEO of electric car firm Tesla has said he wants to "defeat" spam bots on Twitter, make the algorithms that determine how content is presented to its users publicly available, and prevent the platform from becoming an echo chamber for hate and division, even as he limits censorship.

Yet Musk has not offered details on how he will achieve all this and who will run the company. He has said he plans to cut jobs, leaving Twitter's approximately 7,500 employees fretting about their future. He also said on Thursday he did not buy Twitter to make more money but "to try to help humanity, whom I love."
