That's one point of view, but you just banned unlimited-on-your-phone plans that a lot of people presumably enjoyed. If they change them to simple unlimited plans, you'll be popular. If they only offer limited plans now, you'll be unpopular.
We have a number of mobile services in the UK who explicitly offer routers with WiFi slots for replacing your home broadband with unlimited SIMs. I have used them in the past to replace the wired internet when there has been line maintenance that took out the broadband for a couple of days.
4G alone can get you a nice stable 100Mb/s.
You seem to be defending a shitty deal that happening in North America, without any clear reason.
