Yeah... and that is pretty much taking a service without paying for it. I can see why some people would prefer free streaming over paying for Cable or Sat.Hogwash. I don't know of anyone who uses an IPTV service and shares or steals content. Most of these people use a Roku to stream, so how would they offload the content, even if they wanted to? Usage of IPTV is driven by convenience, access, and price. Now if you're talking about sharing usernames/passwords, sure people do that.
Yeah, that is probably not as common.But people also have multiple satellite dishes with multiple receivers at different addresses
