First off, I had high hopes for chargify as I had chatted with Lance on a few occasions and he comes off as a great guy. But David here comes off as a total ass. He literally stated that only 99.1% of their users are free users, and then proceeded to rip on free users like crazy. I can understand the pain of servicing free users. I have 10+ messages/questions a day from free users and they often are rude or incredulous. That doesn't mean I can say "all you people who bug tested our software, reported deficiencies and helped ensure our service doesn't suck, go take a hike!".

Just because you got your use out of the free customers (their time dealing with your buggy early release software) doesn't mean you can jettison them. You have to ease them into a new pricing system, stop future people from being free, etc.
