Educational activities, including schools of all levels from kindergarten to university, have a moral duty to <a href="/education/education.html">teach only free software.</a> 
Why, after all, do some proprietary software developers offer gratis copies<a href="#note1">(1)</a> of their nonfree programs to schools? Because they want to <em>use</em> the schools to implant dependence on their products, like tobacco companies distributing gratis cigarettes to school children<a href="#note2">(2)</a>. They will not give gratis copies to these students once they've graduated, nor to the companies that they go to work for. Once you're dependent, you're expected to pay, and future upgrades may be expensive.
