Why open core software is bad for the FOSS movement.
Nothing is inherently anti-business about Free and Open Source Software (FOSS). In fact, a number of different business models are built on top of FOSS. The best models are those that continue to further FOSS by internal code contributions and that advance the principles of Free Software in general. For instance, there's the support model, where a company develops free software but sells expert support for it.
Here, I'd like to talk a bit about one of the more problematic models out there, the open core model, because it's much more prevalent, and it creates some perverse incentives that run counter to Free Software principles.
