I used that example because it's a real-life problem my parents have faced, you're paying for DirecTV and also Starlink? That's going to be closer to $300+/mo. If you just had high speed internet and HuluTV (or similar) you'd be paying a lot less. Many people that live in rural areas simply can't afford both.
Your parents aren't able to simultaneously stream with 40mbps?
The example was 2-3 simultaneous streams plus a "work environment" (a zoom call?). My family of 4 doesn't ever have that much usage, which is why I don't enjoy being forced to pay for 75mbps — Comcast's lowest tier. We cap out at two simultaneous streams, which is probably the same for your parents. It has literally never been an issue — even when we had 25mbps.
