The ongoing feud between tech giants Elon Musk and Mark Zuckerberg escalated over the weekend, with both CEOs trading barbs online following the launch of Meta's Threads platform. The new app, seen as a direct competitor to Twitter, has sparked accusations of copying and threats of legal action from Musk.

The latest exchange began with a playful suggestion from the official Wendy's account on Threads, encouraging Zuckerberg to venture into space, a clear nod to Musk's SpaceX. Zuckerberg responded with a laughing emoji, further fueling the online banter.

This online sparring match intensified when a Twitter user, highlighting the exchange, accused Zuckerberg of prioritizing brand speech over free speech, a principle Musk claims to champion. Musk responded to the tweet with a personal attack on Zuckerberg.

Musk's acquisition of Twitter for $44 billion in 2022 set the stage for this rivalry. The launch of Threads, which offers similar microblogging features, has been perceived as a direct challenge to Twitter's dominance. Musk has publicly criticized Threads, labeling it an "Instagram minus pics" and accusing Meta of misappropriating Twitter's intellectual property in a cease-and-desist letter.

While Zuckerberg has refrained from directly addressing the legal threats, he has engaged in subtle online jabs at Musk, often using the word "concerning" with a laughing emoji on Threads, mirroring Musk's frequent one-word responses on Twitter. Adding fuel to the fire, Zuckerberg's first tweet in a decade, a Spider-Man meme, was widely interpreted as a pointed reference to the ongoing feud.
