I remember when cable was analog, channels you didn’t pay for were blocked with a frequency filter. let’s say channels 13-60 were 425-475Hz (purely an example) there would be a little device connected to your coax that would filter it out. The thing was though, they did this in the cable box usually in your yard. So all you had to do was go out at night, pop the box open (wasn’t hard) and remove the filter to get free channels.

Then they moved to digital and all things changed.

If you give the cable guy money for the premium channels then you are still paying for it.
