I find many of the steps you list to be much easier said than done.
add the manufacturer and all its products and services into a personal perpetual denylist
Once I have placed all major publishers of operating systems for Internet-connected TVs "into a personal perpetual denylist", then from whom should I buy a display sized for a living room? And once I have put both Google and Apple "into a personal perpetual denylist" over Google TV and Apple TV, then from whom should I buy a personal mobile phone?
perform a full factory reset on device
How does one select a full factory reset without clicking through the full-screen prompt to waive access to the court system?
I thought this was exactly what we were trying to avoid.
pack up everything in the original box you kept in the attic
I kept the box. My roommate threw it out and compared my objection to those of the characters on A&E's reality TV series Hoarders. How would I go about convincing my roommate not to throw out the box next time?
have chatgpt or gemini write a short listing for the item
I tried to sign up to use ChatGPT, and the sign-up process halted on a demand for an SMS number. OpenAI's help page specifically states that landlines and VoIP are ineligible to activate a new account.
