But, it leaves out that Gail Slater left the FTC to became vice-president for legal and regulatory policy for the Internet Association which is a lobbying group for companies like Google, Amazon, eBay, and Facebook.

The Internet Association—a trade group for big technology companies such as Google, Facebook, and Amazon—spent nearly $176,000 to lobby the California legislature last quarter, according to the Washington Post. It is now running misleading ads on social media asking Sacramento lawmakers to weaken the law.

The group claims that surveillance-based advertising technology, which slurps up and broadly spreads consumers’ personal data without their knowledge, should be exempted from the CCPA. In truth, surveillance-based adtech is one of the worst privacy hazards that the law was designed to stop. It also provides little benefit to online publishers, and erodes trust between companies and their consumers.

Which is a pretty big omission if the argument the founder/CEO made hinges on trying to make people believe Gail Slater having been on the FTC means she fights for little tech.
