I cancelled Netflix many, many years ago when it became clear they were just shoveling junk into their platform. The days of premiere, halo properties like House of Cards are way behind us now.
That said, I know I'm a total outlier in terms of having cancelled Netflix. Their subscriber numbers are doing great. Even their most recent subscriber drop was entirely due to having pulled out of Russia. When I cancelled, I stopped thinking about them (hence my mention of House of Cards, which has been over for many years) and I don't need them to fail or anything.
Also, a lot of the commentary about cancelling due to a crackdown on password sharing feels petty and silly. Netflix hasn't done anything wrong here. They feel that if you use the service in a separate residence, you should pay for it, and that's a defensible position.
