After Meta creator handed out Threads — only days after Twitter CEO Elon Musk was chastised for restricting the number of tweets individuals may view each day — Mark Zuckerberg took to Twitter for the first time in over a decade on Thursday to presumably mock Musk. Following the widespread criticism of Musk’s recent policy changes, Meta formally debuted Threads earlier today. Not shortly after Threads launched, Zuckerberg posted a popular meme of two Spider-Men facing each other. This is Zuckerberg’s first tweet since 2012, and it comes just two weeks after it was revealed that the two CEOs were interested in a cage battle. Hours after Zuckerberg’s tweet, Musk retorted with a jab on Instagram. Taking to his own platform, he wrote: “It is infinitely preferable to be attacked by strangers on Twitter, than indulge in the false happiness of hide-the-pain Instagram.” It is apparent that the Meta CEO is profiting from Twitter CEO’s questionable decisions. Musk, who bought the company for $44 billion in October, immediately reduced it and laid off thousands of people. He subsequently modified content filtering procedures and made Twitter verification a paid service, causing users and advertisers to face a slew of technical difficulties. Furthermore, Musk’s recent move to limit the number of tweets users can view every day — a measure Musk described as “temporary” in order to combat data scrapers and bots — drew widespread criticism from users throughout the world. “There should be a public conversations app with 1 billion-plus people on it,” Zuckerberg said in a post on Threads. “Twitter has had the opportunity to do this but hasn’t nailed it. Hopefully we will.”
