However, McGregor once joshed Zuckerberg after the coding wizard changed Facebook's name to Meta. View this post on Instagram Instagram PostMark Zuckerberg intends to embrace all of the company's brands, including Whatsapp and Instagram, by adopting the name Meta:"Right now, our brand is so tightly linked to one product that it can't possibly represent everything that we're doing today, let alone in the future."McGregor, however, wasn't initially thrilled by the idea initially. He wrote on Twitter:"Mate. Leave it out."He quickly deleted the tweet later. Conor McGregor has been sidelined from action owing to a leg injury he sustained in his third fight against Dustin Poirier at UFC 264. Zuckerberg replied to McGregor's comments under his Instagram video by claiming that he's excited about his return.Conor McGregor@TheNotoriousMMAI’ll be back! For the sake of humankind!
