Seeing all this negative press about NYT (their website's weird trackers) and spotting increasingly more propaganda articles in their editorial section in the recent past, I am now going to stop my NYT subscription.
I gave up on them years ago when I noticed so much editorialization outside of their opinion section. Their news has become opinion; their opinion has become propaganda.
Other comments on this thread are suggesting switching the mode of payment to PayPal which let's you cancel instantly. Or credit card chargebacks if you can document that you exhausted reasonable efforts to ask NYT to cancel the subscription
The last thing they deserve is my money.
