It's a number of factors....
Whatever you call it. I'm a cord cutter.
Set up OTA as insurance against cable failure (happened last earthquake for a few days). Discovered that the signal was much cleaner - so it's a picture quality issue.
Got a roku box and found that I was watching Netflix much more than cable channels - so it's an alternative source issue.
Content on cable channels gradually got dumbed down - The Learning Channel is now a multiple birth reality show channel. Arts & Entertainment is Gene Simmons. There's no M in MTV any longer. - so it's a quality issue.
Had to contact customer service for a few questions. Surley CSR's who gave wrong answers and were no help at all - so it's a customer service issue.
Got my bill on a monthly basis and realized that I'm not really using or enjoying a service I pay for - so it's an economic issue.
Catagorize me however you wish, but I call myself a cord cutter
