I’ll push back on that a little. Peloton has, from the beginning, been a very closed ecosystem.
Contrast this to the smart trainer I have which is marketed to cyclists (a Wahoo KICKR). It uses standard protocols to talk, and while they have some software available, it works independent of their ecosystem on standards compliant equipment (ANT+ and BLE). You can even talk to it using the open source GoldenCheetah software.
I would say I own this device. Sure I can’t necessarily hack the firmware easily, but I can’t hack the firmware on my microwave easily either, but I’d say I own that, too.
