For about a decade the practice sat in a space where the companies knew about it, tolerated it and sometimes joked about it, so no norm ever had to be settled. Roughly one in three subscribers shared an account with another household. Terms of service always said otherwise: accounts were personal, non-commercial and household-limited. But the clause went unenforced, and an unenforced rule teaches nobody what is acceptable. That changed from 2022, when Netflix began restricting access by IP address to identify out-of-household use, then introduced paid options to add people and moved to end free sharing altogether. The legal position was never as vague as the social one: in the UK, sharing credentials for a streaming service without authorisation is treated as copyright infringement. The polling, taken in April 2022 as the enforcement wave began, catches the norm mid-argument: 36% say it is fine, 42% say it is not, and an unusually large 22% say they are not sure, which is what a question looks like before a society has agreed on the answer.
