Free software does indeed seem like a good thing to require in our society-cornerstone systems: schools, hospitals, government systems etc.

Experiencing a a slight dip does not mean that the general trend has not been good.
Or to put it in a way more people will understand: Society is going to moon, so buy the dip and hodl on.
Many of the books studied in schools are copyrighted and deny the freedom to distribute (Freedom 2), or to distribute modified versions (Freedom 3). Books aren't the same as software though. Unlike a book, software does stuff. It can act against your interests. There are many ways proprietary software can be harmful, [0] few of which apply to non-Free books.
It's the same reason the FSF have a strong position that game engines should be Free Software, but they aren't too concerned if game assets (maps, textures, music, etc) are paywalled and non-Free. A texture can't do harm in the way executable code can (not counting malicious textures that exploit security vulnerabilities).
(Incidentally this is the current licensing situation for DOOM and Quake. The engines are Free and Open Source Software, but the game assets are paywalled and non-Free.)
Studying patented technologies might not always be a mistake, as it may represent the state of the art, and still be worth studying. I believe the NOTAR helicopter technology is patented, for instance, but it's still worth teaching to aeronautical engineering students. [1] Again, the issues there aren't the same as the issues with non-Free software. The issue of companies paying schools to teach their solutions, is a different matter.
The easy bit will be to not repeat Stallman's faults. Stallman would often come across as pedantic and combative in the Q&A session at the end of a talk, for instance, and would say absurd things such as that people who make proprietary software should be imprisoned.
