I disagree. If it is standard practice to BYOR, family or friends might give one to grandma, saying "use this, it will save you money".

I used to install satellite TV and saw this all the time. People would get old receivers from friends and family. Fortunately for me, the receivers were proprietary to that service (we don't use generic pay TV receivers in Canada) and the old ones were built like tanks. If people could have supplied any old cheap generic receiver, I probably would have had a bad time.
