Technically, the Peloton Tread+ is a treadmill that's meant to do one thing: Play Peloton content. Unless you jailbreak your Peloton, you can't watch Netflix or listen to your own music, as you might with some of the fancier treadmills at the gym—at least, not without voiding the warranty. If a manufacturer changes the software of your device, well, it's their software. Generally speaking, it's good security hygiene to update your software to the latest version whenever they're made available. (This is true with Pelotons, too, which recently had two security issues .) So you can't legally modify the Tread+'s software and it's not a good idea to forgo updates. That means you can either ask for a refund or deal with it. At the end of the day, you're actually just licensing the hardware—even if you paid to own it.
