President Barack Obama this week signed into law tighter restrictions for the agency, barring the organization from mass collection and storage of American phone records. Snowden, the man who revealed these practices to the public, is in the New York Times Friday, celebrating the work of Congress and the President as a “profound” achievement, and “a historic victory for the rights of every citizen.” Still, Snowden believes surveillance reform has a long way to go.

Here are some other choice quotes from the article:

• Snowden had worried at one point that he might have, “put [his] privileged lives at risk for nothing — that the public would react with indifference, or practiced cynicism, to the revelations.” But the changes to the law have, in part, vindicated his decision to risk imprisonment by leaking classified information
• He calls this weeks events, “only the latest product of a change in global awareness,” citing other events like The U.N. declaring “mass surveillance an unambiguous violation of human rights,” as evidence of a broader movement to curtail spying powers.
• He also laments that there is more work to do. Writes Snowden: “the right to privacy . . . remains under threat. Some of the world’s most popular online services have been enlisted as partners in the N.S.A.’s mass surveillance programs, and technology companies are being pressured by governments around the world to work against their customers rather than for them.”
