Elon Musk now owns Twitter but the EU is watching carefully lest the self-styled "free speech absolutist" turn the social media site into a platform for hate speech.

After Musk tweeted "the bird is freed," Internal Market Commissioner Thierry Breton responded with a wave emoji and "In Europe, the bird will fly by our rules."

Musk’s takeover — reported Thursday night — could have huge implications for the future of the site, especially if former U.S. President Donald Trump is allowed back on the platform, and if Musk loosens the rules to prevent the spread of hate speech and misinformation.

Musk promised Thursday that the platform would not become “a free-for-all hellscape where anything can be said with no consequences.”

Breton's tweet was accompanied by the hashtag DSA, a reference to Digital Services Act — which requires providers of digital services to take swift action against illegal online content, such as hate speech.

The commissioner also tweeted a video showing him and Elon Musk in May after discussing the Digital Services Act.

In the clip, Breton tells Musk "I was happy to ... explain to you the DSA, a new regulation in Europe " and Musk replies: "I agree with everything you said."

"That's what he said," Breton tweeted Friday.
