What about the one sided ability to change a contract??

A year from now Roku pop up says "Click to Accept" , the text says **"this contract means you'll have to give us your first born child? ** My reasoning says if they can do one then they can do the other. There is nothing that would prevent them from adding 'fees', or 'subscriptions' or simply turning off the device. (!)

This is egregious. We bought something. In normal commerce, the contract was set in stone at that moment. The seller can't roll up 2 years later, change the contract, force you to agree before you can use your device, and then say , well maybe if you beg, you can opt out.
