I feel that the direction things are moving, those two categories of software will eventually be the same thing. FOSS was most prominent at the bottom of the stack, first kernels, then major libraries, then UI engines, toolkits, game engines and so on. Once open source reaches the level of web-app, the users will be directly interacting with a program that's open source from top to bottom. The things on top of that are data, content, support and other things businesses add. Maybe next those will be become open too. Or maybe a new layer of proprietary solutions will emerge above the current stack (VR?), and open source will scramble to catch up.
