I think it's pretty ridiculous for Netflix to define what is and isn't my "household".
What if you have friends who are basically family who more-or-less live with you? Are they not part of the "household"? "Sorry, Bob, while you maybe my daughter's godfather and donated a kidney to me, you're now going to need your own Netflix account because Netflix wants to mash the 'pump corporate profits' button that has been a primary contributing factor of both embarrassing wealth transfer from the poor to the rich and inflation post-pandemic."
