"Companies that promise that their service is secure or encrypted, but fail to use end-to-end encryption where appropriate, may deceive consumers who reasonably expect this level of privacy." Furthermore, "certain circumstances may require the use of end-to-end encryption, and failure to implement such measures may constitute an unfair practice." The weakening of encryption or other security measures to comply with laws or requests from a foreign government may therefore violate Section 5 of the Federal Trade Commission Act, the document states.

The National Guard stand solemn watch at the Krispy Kreme tonight. I cannot tell if they defend the people from the donuts, or the donuts from the people. Powdered sugar hangs in the air like cannon smoke. Jensen took a hot coffee to the face, he may never recover.

Our Response to Mississippiโ€™s Age Assurance Law - Bluesky A new Mississippi law requires us to block full access to Bluesky unless all users complete age checks. We have concerns about this lawโ€™s implementation.

The balkanized "future" of the internet has long been here--for decades the internet in Spain has looked very different from the internet in Canada.

But I think this is one of the first times we're seeing a platform geo-blocking by *US State* and this way lies madness.

The law requires "verification for all users, not just those accessing age-restricted content." This is a bad time for people who need anonymity to be subjecting their online activities to scrutiny.

Unfortunately, Bluesky is unavailable in Mississippi right now, due to a new state law that requires age verification for all users.

While intended for child safety, we think this law poses broader challenges & creates significant barriers that limit free speech & harm smaller platforms like ours.
