ChainCatcher reports that Ethereum co-founder Vitalik Buterin urged Musk to "cool it" as his platform sparked a new free speech controversy in the heated debate over foreign tech workers.

Musk publicly supports the hiring of foreign tech workers by top U.S. companies, a move that has sparked outrage among conservatives on X, who believe that hiring conditions in the U.S. are increasingly unfavorable to domestic citizens.

Vitalik stated that while he admires Musk's willingness to fight for free speech, he urged the Tesla CEO to "cool it," tone down the "rhetorical tone," and stop using the "social media banhammer" to shut down X accounts.

Vitalik stated: "It's easy to respect free speech when we agree with the speech, and hard when we find the speech terrible. But the reasons for respecting free speech remain unchanged: today the ban is in one party's hands, and tomorrow it may be in another's."
