I would like to know how much of this has been tested in court, and how much has just been insinuated by the sheer volume of corporate lawyers insisting that they're allowed to pull this crap. Because you can just write any old junk down, but lawyers don't make the law.

Like, on the basic level of what a contract is, how can one party reserve the right to unilaterally change the terms? How can an EULA be binding when the exchange has already happened and no agreement was made except the delivery of a product? How can consideration be forced on one party while their property is held ransom? And esepcially how can a fundamental legal right be waived in such a manner?

If this happened in any other sphere it would be understood as some kind of vandalism, theft extortion, or something. Like your builder just shows up one day, "Hey, I installed a new sink in your kitchen! You can't use your house until you agree I'm not liable for anything that happens to your house from this point forward. No, you can't read it, just sign it. This is a real contract because I gave you something of value." I suspect this isn't happening because it's perfectly legal, but because the internet of things hasn't matured enough to have strong legal precedents established and there hasn't yet been a big public backlash against it.

I think the more they try to pull this garbage the more people will start to realise that this is bullshit and do something about it.
