Most proprietary companies will give very steep discounts or even free licences to schools and universities. If you introduce an entire generation of students to your software, students will gravitate toward what they're familiar with when they enter the "real world".

I'm not. Universities aren't places of open or free learning. They're deeply invested in capitalism and benefit greatly from intellectual property laws. In fact, most universities function largely as state subsidized pipelines that take people without a viable, real world skill set and turn them into people who still don't have a viable real world skill set, but who do have a piece of paper telling corporations that they're able and willing to put up with complete bullshit, general mistreatment, and dull, grueling labor for years without incident. Which is good enough for your typical middle-class wage slave and whatever they might want to do.

Why show young bright minds free options when you can get more money from them for the rest of their lives with subscription software
