And this smells of fraud.
If it was a real sale, then they could not do this remote control/deletion at a distance.
Shit I buy at Walmart can't be physically taken away from me later on. Its legally mine.
This? Its fraudulently sold as a "sale" but is really an indefinite rental with the terms of "fuck you I'll do what I please when I please".
And on top of fraud, I'd also throw in the CFAA as well, a criminal statute. Its established law that if I set a timebomb in software at $company where if I'm fired/laid off, that's criminal access. No boilerplate from some shitty clickwrap can excuse criminal law.
Time to start jailing Sony execs and the like.
