And encouraging and requiring open-source software development in Europe, founded by non-profit organizations and government. With requirements and control. The base for solution is readily available with Linux and BSD. Our politicians and CEOs only think in short terms. As consumers do :(
We can ban or tax things, like shipping Laptops with proprietary operating-systems. Declare, that the pre-installed operating-system must be open-source with {GPL, MIT, BSD} and fulfill standards. If not? Fine. Ship it without an operating-system.
And teach kids at school about scale of software and vendor lock-in. Every monopoly starts with being lazy and just grasping the first solution...
