It's not that hard. I required my kids to grow up with Libreoffice (and Openoffice before that). There where hassles but they where manageable. I made sure to explain why this restriction was in place. I also was willing to fight any battle with school authorities over this issue should the need arise. Fortunately that was not necessary.

I did the same. It turned out that teachers were perfectly fine using Open/LibreOffice.
