California legislators on Thursday adopted sweeping new rules that restrict the data-harvesting practices of Amazon.com, Facebook, Google and Uber, a move that soon could spur other states and Congress to take aim at the tech industry.
The California Consumer Privacy Act is one of the toughest U.S. regulations targeting Silicon Valley, where recent privacy mishaps — many involving Facebook — have left consumers clamoring for greater protections online. The law requires tech giants to disclose the kind of data they collect about consumers and allows Web users to opt out of having their information sold to third parties, including advertisers.
The new privacy rules, which are slated to come into effect in 2020, apply only to residents in the Golden State. That leaves time for corporate critics such as AT&T, Comcast, Facebook and Google to resume lobbying aggressively to revise it over the next year.
