#1) It's a business decision to piss off the people who tried your service? Maybe I can't afford it now but I sure can recommend your business to my friends who can. Also, I'm sure if it were your business you'd rather have me praising it on social media instead of bad mouthing it. It might be a business decision, but it's more stick than carrot.
#2) This is an outdated method of retention that simply insults the people who took the time to try your service. Very few other websites that offer free trials make you contact customer support to cancel. Why would you put yourself behind the competition?
#3) If they are likely to never sign up whose fault is that? Is it mine for not finding the service worth the money or yours for not setting your price point at a place that matches the value of your services? Maybe its nobody's fault so maybe the potential customer shouldn't be punished.
#4) This just smacks of bait and switch. When you sign up for a free trial they show you a welcome video and tell you to go to billing and simply press cancel. However they stop there and fail to mention that pressing cancel just bring up a window that tells you to contact customer support.
