Opensource

Educating users is much needed effort for open-source community, it's also an unpaid and thankless job.

Google had made a huge progress by providing many schools with Chromebooks, but their target is profit and locking users into Google Docs, the fact that ChromeOS is Linux is just a coincidence.

Again, when you try to make some university buy Linux-based laptops, there will be Windows and Mac advocates popping up immediately, because the person making the decision usually gets the business side of things but not technical side, and Microsoft representatives will have convenient PowerPoint slides how their office suite is the industry standard and how you'll save lot of money later if you buy their Windows laptops now, with preinstalled MS Office, and they will give you a discount too.
