Filtr: Device-level ad blocker for Apple apps
Filtr is a new device-level ad-blocking feature bundled into the Wipr app that blocks ads and tracking across iPhone, iPad and Mac apps by using Apple’s new URL filters in iOS 26 and macOS 26. Built by developer Kaylee Serena Calderolla (creator of the Safari ad blocker Wipr), Filtr uses a locally stored “pre-filter” blocklist with server-side confirmation routed through Apple as a proxy to avoid revealing who queries the list. It prevents most third-party ad network requests but does not block ads served from the same domain as the app (so apps like Facebook, Google and Reddit may still show ads). Wipr costs $5 and Filtr is an optional paid feature ($5/year or $25 lifetime). Calderolla says Filtr is the first app to use Apple’s URL filters feature.
Uses a new Apple platform feature (URL filters) to enable device-level blocking across apps, which directly affects in-app ad delivery, tracking, and publisher/app monetization across Apple’s ecosystem.

US suspends Microsoft, Adobe from green card labor program
The Trump administration has suspended Microsoft, Adobe, and six other major tech firms—Capgemini, Cognizant, HCL, Infosys, Tata, and Wipro—from the U.S. Permanent Labor Certification program, which facilitates green cards for skilled foreign workers. Secretary of Labor Keith Sonderling cited active federal investigations and alleged fraud, noting that no new or pending applications from these companies will be accepted. Vice President JD Vance accused Microsoft of replacing laid-off workers with H-1B visa holders. Microsoft defended its practices, stating that most U.S. employees are American and that 80% of its H-1B petitions were for existing employees. The announcement was made during a White House summit on H-1B fraud, and the administration also plans to investigate nine universities, including Harvard, Yale, and Stanford, over student visa program abuse.
