Tell the FCC how much data caps suck and how--if anything--it should be illegal for companies like Comcast to exempt their own services from the data caps. If their IPTV-based "cable" service is streaming 4k video 24/7 that should be included in a customer's data usage otherwise it's an abuse of a monopoly over the user's connection!
Even if they didn't ban caps outright the caps would disappear overnight if companies were forced to include their own services in customers total data usage figures (because 4k streaming TV services would eat up 99% of the average user's cap in like three days LOL).
