"If they can demonstrate that you have to click through the ToS to use the device and app ..."

There's nothing to demonstrate. We will have no interactions.

The op implied (probably correctly) that their ToS is toxic. I am pointing out that there is no reason for you to enter into that ToS.

Are you suggesting that I, an anonymous piggyback user of their service, would blow up my anonymity (and all of the protections and peace of mind that it affords) by attempting to reestablish some form of legal contact ?

No. It's easy come, easy go and that's just fine with me.
