Yes, I get your point and I think there's a lot of truth in it. Why should they pay a Euro more!? It's an experiment, though. Let's see how it will turn out!
I think one of the reasons I'm (trying to) do it transparently is because I can get an idea of how the company works and how the people working there think. If they're not willing to pay a symbolic euro for open source software they're using in the products they're making thousands if not millions of Euros with, I'm not sure if they're valuing other people's time and work enough that I will want to work for them.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
