Real free to air satellite is legit, that's picking up the few free, unencrypted, channels.. normally people use the big dishes for that. It looks like the satellite pirates are also co-opting the same term to mean picking up encrypted DSS digital satellite and using hacked keys.
satellite companies are currently in the process of shutting down these free tvers
The process of shutting down people watching encrypted channels free is ongoing. It's a constant arms race with changing encryption keys and new firmwares for the smart cards, and etc. It's been going on since the dawn of encrypted channels and will probably go on forever, because there's no 100% solution for solving the mass-broadcast DRM problem.
