Personally, I use ERP/CRM for small company which is free software and we pay the developers 150$ for each release. We pay developers for their work, not for software - which is free for everyone, unrestricted to use and improves further.
I also have a friend who runs a small professional precision technique workshop, who is tired to pay Solidworks 600$ for each useless version just because he needs support, otherwise he gets nothing.
He expressed the desire to find a CNC software that is freedom based and pay on regular basis for the features he wants to be implemented.
I really hope, Windows will die together with such stupid mindset, for that mindset alone was the reason for windows monopoly.
