This Week in Privacy: Mar 16-22, 2026

Instagram to Remove End-to-End Encryption from Private Messages
Meta quietly announced that Instagram will stop encrypting private messages between users starting May 8, 2026. The company disclosed this significant privacy rollback through updates to its help page rather than a major announcement, marking a reversal after years of expanding encryption features. This decision follows sustained criticism from law enforcement and child safety groups who argued that encryption hindered investigations into illegal activity. The change will affect Instagram's massive user base, potentially exposing private conversations that were previously protected from outside access, including from Meta itself.
Telus Digital Confirms Massive 1 Petabyte Data Breach
Telus Digital acknowledged that hackers successfully breached its systems and accessed approximately 1 petabyte of data. To put that in perspective, one petabyte equals roughly one million gigabytes, enough to store hundreds of millions of documents or years of video footage. The company publicly confirmed the breach on March 18, though details about what specific information was accessed or how many individuals were affected remain unclear. This stands as one of the largest data breaches by volume disclosed this year.
FBI Confirms Purchasing Americans' Location Data Without Warrants
During a Senate Intelligence Committee hearing, FBI Director Kash Patel confirmed that the agency purchases commercially available information to track individuals' movement and location without obtaining warrants. Patel defended the practice as consistent with the Constitution and federal privacy laws. However, Senator Ron Wyden criticized this as circumventing the Fourth Amendment and the landmark 2016 Carpenter v. United States ruling, which requires law enforcement to obtain warrants for location data from cell service providers. By purchasing data from commercial brokers instead, the FBI may be exploiting a loophole to access information that would otherwise require court approval.

The Big Picture
This week reveals an uncomfortable reality: personal data breaches have become so routine that 17 separate incidents in one week barely registers as unusual. More concerning is the erosion of privacy protections happening through both corporate decisions and government practices. Instagram's encryption rollback and the FBI's acknowledged purchases of location data suggest a broader retreat from privacy safeguards, whether driven by law enforcement pressure or commercial convenience. As multi-million dollar breach settlements become standard business expenses and petabyte-scale data theft becomes possible, the question is no longer whether your data will be exposed, but when and how many times.
