Nice article. I agree with the fact that a common mistake made in Open Source is thinking that is free.

Another mistake(in my opinion) is to automatically think that all your requirements are met when using Open Source software and that it requires no tweaking, adjusting or training. I have experienced this myself during my work with Open Source Products.

A price you have to pay to work with Open Source is to find out how the product works(which in my opinion is fun). As you know “time = money” so in that case you can really say it’s not free
