No, all that means is you're breaking the TOS. They don't have the power to establish a whole new, made up legal definition of "stealing" in an end user license agreement.
Strealing doesn't always mean illegal, but whatever helps you sleep at night..
I mean, i don't realy care, i "steal" movies/TV shows eveyday on the streamng apps i use on my Firestick... But I'm not gonna pretend I'm not doing it...
