Established paid products always give us trouble yet we are being negative on free ones..

Since the day I started using Skype I realized that whenever I am about to use a new technology ( especially a free one ) I always face it with a grain of skepticism and I am being negative when I encounter the first glitch, while what I should do is complain about the paid counterparts bad service ( e.g. Cell phone usage ). I do acknowledge that Skype for instance has its problems, but then again it’s free, while my cell phone carrier costs me a ton of money and cell phone reception is on occasions as bad as a Skype call can get.
On the other hand you have people complaining how hard it is to use a Linux distro and that using it can lead you to frustration all the while forgetting that using Windows can be the biggest pain in the a$$. So unconsciously we seem to forget all the faults of a paid program or service because we face those problems every day and we know they are there for sure and we seem to bitch whenever we hit a small problem on free and open source products. Perhaps we should think twice the next time we are about to curse on free stuff and instead we should turn that negative energy towards the more established cash draining resources.
