Privacy activists are rallying in Washington, D.C., today to oppose a bill they say would expand mass surveillance. Critics say the Cybersecurity Information Sharing Act, or CISA, would allow corporations to share users’ personal information with the government under the guise of cybersecurity. This week, Apple joined the growing list of more than 20 top tech companies to oppose CISA, saying, “we don’t believe security should come at the expense of privacy.” Oregon Democratic Senator Ron Wyden criticized CISA during a Senate debate Wednesday.

Sen. Ron Wyden: “I believe this bill is badly flawed, because it doesn’t pass the test of showing that when you share information you’ve got to have robust privacy standards, or else millions of Americans are going to look up and they’re going to say that’s really not cybersecurity. They’re going to say it’s a surveillance bill.”
