In 2010, Steven Levy, who wrote the 1984 book Hackers: Heroes of the Computer Revolution, wrote that Zuckerberg "clearly thinks of himself as a hacker". Zuckerberg said that "it's OK to break things" "to make them better". Facebook instituted "hackathons" held every six to eight weeks where participants would have one night to conceive of and complete a project. The company provided music, food, and beer at the hackathons, and many Facebook staff members, including Zuckerberg, regularly attended. "The idea is that you can build something really good in a night", Zuckerberg told Levy. "And that's part of the personality of Facebook now ... It's definitely very core to my personality."

In June 2010, Paul Ceglia, the owner of a wood pellet fuel company in Allegany County, upstate New York, filed suit against Zuckerberg, claiming 84 percent ownership of Facebook and seeking monetary damages. According to Ceglia, he and Zuckerberg signed a contract on April 28, 2003, that an initial fee of $1,000 entitled Ceglia to 50% of the website's revenue, as well as an additional 1% interest in the business per day after January 1, 2004, until website completion. Zuckerberg was developing other projects at the time, among which was Facemash, the predecessor of Facebook, but did not register the domain name thefacebook.com until January 1, 2004. Facebook management dismissed the lawsuit as "completely frivolous". Facebook spokesman Barry Schnitt told a reporter that Ceglia's counsel had unsuccessfully sought an out-of-court settlement.
A movie based on Zuckerberg and the founding years of Facebook, The Social Network was released on October 1, 2010, starring Jesse Eisenberg as Zuckerberg. After Zuckerberg was told about the film, he responded, "I just wished that nobody made a movie of me while I was still alive." Also, after the film's script was leaked on the Internet and it was apparent that the film would not portray Zuckerberg in a wholly positive light, he stated that he wanted to establish himself as a "good guy". The film is based on the book The Accidental Billionaires by Ben Mezrich, which the book's publicist once described as "big juicy fun" rather than "reportage". The film's screenwriter Aaron Sorkin told New York magazine, "I don't want my fidelity to be the truth; I want it to be storytelling", adding, "What is the big deal about accuracy purely for accuracy's sake, and can we not have the true be the enemy of the good?"

Zuckerberg founded the Start-up: Education foundation. On September 22, 2010, it was reported that Zuckerberg had donated $100 million to Newark Public Schools, the public school system of Newark, New Jersey. Critics noted the timing of the donation as being close to the release of The Social Network, which painted a somewhat negative portrait of Zuckerberg. Zuckerberg responded to the criticism, saying, "The thing that I was most sensitive about with the movie timing was, I didn't want the press about The Social Network movie to get conflated with the Newark project. I was thinking about doing this anonymously just so that the two things could be kept separate." Newark Mayor Cory Booker stated that he and New Jersey Governor Chris Christie had to convince Zuckerberg's team not to make the donation anonymously. The money was largely wasted, according to journalist Dale Russakoff.
