I hope not, ONE of the reasons I am keeping Dish is because of my data cap from Xfinity - the 2TB DVR and live programming is key in me consuming content and NOT using data. Of course, if I were to cancel Dish I could use that money saved and upgrade to the 30/month unlimited plan but then when there is an outage, I would only have OTA content to watch instead of Dish and OTA. Admittedly, outages are rare (last one was May 2020) and it has improved in my area significantly - yes, when there is rain/signal loss I can't watch live programming but at least I can watch DVR recordings and rain outages don't last long and Dark Sky is much better indicator of when I can expect my service to come back than COMCAST ETA alerts.
IF the faster internet speeds come to rural as planned (I know, don't hold your breath; it may take longer than we think), then I could see Dish going the cheaper route of 4K via Sling TV. However, as you pointed out, the datacaps are a different story. At this point with Dish being a shrinking business, I don't see Dish caring too much about people with low datacaps.
On the positive side, I think this new Admininstartion is going to be far more demanding of ISP's than the previous Administration. So, we could see some realy action on datacaps, which is a BS limitation, and if you don't think so, I invite you to research that. On the other hand, SPEED, is a ligitimate attribute for limits in a tier pricing model.
Bottom line, I really do think datacaps are going to be a big issue with the
new FCC, and I would not be suprised to see the FCC put ISP's back under Title II, where it belongs. And I hope the new FCC will greater push to serve rural areas with adequate speed.
Where I live, only ONE sufficiently speedy option is available to me at 200mps down for $73+change per month (and they keep trying to entice me to upgrade to 400mbs for like for over $100 per month). That's the ONLY (lowest) price/plan offered; it is their "Base" or "Standard". I would like the option of say, a 30mps down for $30.00 per month (I'm just throwing out numbers) or some sort of tiers that each of us can choose that fit our needs. I (and I think the vast majority of households) do NOT NEED 200mbps. I am certain I can do well with between 30-50mpbs at a lower price becasue of multiple accounts/users on the net streaming HD content at the same time. And many single or two person households can get by with 10-20mps at an even lower price. But we shall have to wait and see what the new FCC really does.
