Hello Johannes, The original article is warning traditional market participants that open source means giving your blueprints away. Yes, you have the option of giving away only part of your designs. For those of us not interested in domination games, the larger point is that openness and price can be orthogonal. We can engage with the old system while developing it's replacement. My favorite example is RedHat, for which the word 'harvest' seems to fit quite well. Fedora Linux is a community project fostered by RedHat and every few years they will take the latest version and further develop it for commercial users which must (and are more than willing to) pay a lot of money. Users without money can then take advantage of RedHat's engineering efforts by using one of the RHEL derivatives such as CentOS or Scientific Linux. -Karl
