If it's harder to leave than it is to join, then I'm not using your stuff. It's mildly condescending and very transparent and so I don't want/need to deal with it. If you believed in your product, you wouldn't do it. I subscribed to the New York Times with a simple one-step "put in your credit card deets". One year later I was going to leave the country so tried to cancel it. After several steps of forms you get the…
I told them if I had to call, I would call my lawyer first, who would be calling them... and then they wrote back that they canceled.
So, these companies don't need to make you call, and even if it's inconvenient, difficult, or impossible to call to cancel, some won't budge. This should be illegal; if I sign up online, I should be able to cancel online. Making these artificial steps hampers business, my work time, my personal time... sitting on a phone waiting or slogging through steps or upsells is not a good way to do business and interferes with everything else.
It hasn't bothered the politicians enough, who are corporate shills anyway, so they haven't made it so companies have to be reasonable with this, like they did with CANSPAM.
