Apple’s letter was sent to Dick Durbin, the Senate Judiciary Committee chair, as well as its top Republican, Chuck Grassley. It was also sent to antitrust subcommittee chair Amy Klobuchar and its top Republican, Mike Lee.
In a previous letter to top Senate lawmakers on February 3, Apple said the Open Markets Act would harm user security and privacy. Sideloading “would enable bad actors to evade Apple’s privacy and security protections by distributing apps without critical privacy and security checks.”
The Open Markets Act is an antitrust bill that applies restrictions to Apple, Google, and other platform holders. It would ban policies preventing…
