That conversation is very sad --- an absolute textbook example of how not to handle this kind of issue. Instead of complicated, technical and annoyed explanations of what Linux was to someone who obviously just doesn't care, the simple statement that: Sorry, we make components for websites. This just means that your web people are using one of our components and has set it up wrong. You'll need to talk to your IT people; they'll be able to point you at someone who can help. ...would have gone a long way towards defusing the situation. Given their first reply ('...we produced it for free and you are able to use it without paying us ... and are even threatening to have us arrested...') no wonder the conversation went badly. That's just being an arsehole.
