The second suit filed by the FTC is set to be filed later this afternoon. The cases accuse Facebook of illegally using its power for more than a decade to push out rivals and buy out rising competitors, noting WhatsApp and Instagram as specific examples of this. Facebook has continued to purchase multiple companies despite recent scrutiny, Breitbart News recently reported on Facebook's purchase of the customer service startup Kustomer in a deal valued at more than $1 billion. The suit is part of the latest escalation in the power struggle between world governments and U.S. tech firms. In October, the Justice Department and a smaller group of U.S. states filed a similar antitrust lawsuit against Google. Facebook has denied being a monopoly, noting that it ranks behind Google in how much revenue it takes from the $160 billion global market for online advertising. Google and Facebook maintain a duopoly over the online advertising market.
