What are the after-sales terms? Is there a contract? Are you going to pay for an after-sales subscription? If not, how is their business model to finance it? How is your privacy or personal identification involved? How long will the product be supported (Planned obsolescence)? Can you block automatic-updates? Can you downgrade the firmware? What are your legal options if they close down the service before product end-of-lifetime? Or liability if the product gets hacked and destroys/damages property? Will refusing after-sales influence warranty? What are their terms & conditions to ban your access to the device? What are the non-automated options in case of disputes? What are the options/rights when escalating complaints?
Sounds like these questions should be answered on the box before you (or the person installing it) should open it. Or in the first section of EULA in layman's terms.
