@alexbuzzbee @alvarezp This is my thought, too -- some really, really shortsighted attempt at defense against some sort of attack.
That being said, I wonder how broad this "linux prevention" goes -- I've been using the wonderful, third-party site "playapplemusic.com" to use Apple Music on the web (since Apple doesn't provide a web interface, or even let you download the Apple Music app on ChromeOS), and it went down about a week ago, too.
