As a social media giant, Facebook may face lawsuits from U.S. regulators because of its suspected monopoly, and its market dominance is facing challenges. On Tuesday, Sept. 15, people familiar with the matter were quoted as saying that the US Federal Trade Commission (FTC) is preparing a possible antitrust lawsuit against Facebook, and the complaint may be filed by the end of this year. After the news, Facebook shares fell more than 3% in after hours, and now the decline narrowed to about 1.64%. < / P > < p > prior to this, the U.S. Antitrust agency has conducted an extensive survey on the leading technology giants in the market. Among them, the investigation on Facebook has been conducted for more than a year. The goal is to find out whether the company uses its strong market position to stifle competition, and the investigation has entered a later stage. < / P > < p > according to some people familiar with the matter, FTC continues to ask questions about Facebook’s past acquisitions and how it manages application developers on its platform. As for the acquisition, Facebook believes that the move is not anti competitive, but merely improving the product and user experience. However, FTC has not yet decided whether to sue Facebook, but if it chooses to sue and Facebook loses, FTC is likely to take a series of remedial measures, including restricting the operation mode of Facebook and stripping part of its business. However, it is worth noting that long-term investigation and preparation does not mean that FTC will definitely choose to sue. After all, there is a precedent for abandoning prosecution. In 2013, after a long-term investigation on Google, FTC still decided not to file an antitrust lawsuit against the company. In addition, it usually takes many years for antitrust litigation to be resolved. The U.S. election in November may affect the outcome of any litigation, and the FTC decision may not be so easy to make. Recently, the monopoly of technology giants has been paid close attention by regulators. At the end of July, the CEOs of apple, Facebook, Amazon and Google attended an online antitrust hearing held by the U.S. Congress at the same time, and was questioned by Congress on issues such as anti competitive behavior and suppressing conservative views on network platforms. The rapid growth of FAAG in recent years is obvious in the US market. In recent years, with the stock price soaring, apple, Amazon, Google’s parent company alphabet and Facebook have joined hands with Microsoft to rank first in the market value of American companies. However, members of Congress now doubt how much of the rapid growth is achieved by the real strength of the company, and how much is obtained by plundering and suppressing the monopoly resources of the industry. At the critical juncture when the U.S. economy is under the impact of the epidemic, the confidence and vitality of enterprises need to be improved, which has attracted the attention of members of Congress. At the hearing, lawmakers accused these companies of using their influence to suppress competitors and hinder competition. The hearing focused on Google’s manipulation of Internet search; Apple’s control of apps; Facebook’s acquisition of competitors; and Amazon’s influence over third-party sellers. < / P > < p > all four companies emphasize that they are engaged in healthy competition in advertising, search, shopping and social networking. The hearing may allow legislators to rethink the U.S. Antitrust Law. In the future, it may be easier for the federal government and state law enforcement agencies to investigate or punish large technology companies. On social media, US President trump said on social media that if Congress fails to treat technology giants fairly, he will “sign an executive order and do it in person.”.
