Tesla CEO Elon Musk acquired a 9 percent stake in Twitter to become its largest shareholder at a time

when he is questioning the social media platform’s dedication to free speech and the First Amendment.

The ultimate aim of Musk’s 73.5 million share purchase, worth about $3 billion, is not known.

Yet in late March Musk, who has 80 million Twitter followers and is very active on the site

questioned free speech on Twitter and whether the platform is undermining democracy.

Industry analysts and legal experts are skeptical about whether the mercurial CEO will remain on the sidelines for long

Musk could begin advocating for changes at Twitter immediately if he chooses.

In a note to investors, CFRA Analyst Angelo Zino wrote that although Musk’s intent is unclear

Twitter could be viewed as an acquisition target because the value of its shares have been falling since early last year.

Jack Dorsey stepped down as CEO in November.
