Canada’s antitrust regulator is suing Alphabet’s Google over alleged anti-competitive conduct in its online-advertising business, in the latest regulatory challenge to the tech giant’s dominance.The lawsuit comes after the U.S. Department of Justice (DOJ) said last week that Google should sell off its Chrome browser, following an August court ruling that the tech firm holds an illegal monopoly in search. Canada’s Competition Bureau said in a notice it filed Thursday with the Competition Tribunal, where the case will be argued, that Google “locks market participants into using its own ad tech tools,” and is pushing for the company to sell two of its ad tech tools. Do you think that someone wants to destroy Google ?
