Always free movies NOT free

Why are there movies in the On Demand category “Always Free Movies” that aren’t free? You have to either BUY or RENT. I see this all the time. 

What kind of scam is this? Who organizes these lists and checks them before you publish them? It’s ridiculous. Apparently after looking through past posts here this has been happening for years. Why can’t Comcast get their act together as much as these services cost us??
