Learn to new people about Free Software

I have done most of them.
But still continue and say that they need Microsoft office because most people use it and when they had try to change to libre office the had problem that others cant read .odt files if they using Microsoft office.
Also they are boring to learning new programs and use another OS.

We have any chance to get them in free software ?

If they can't read ODT with MS Office, they need to pay up and update their MS Office or get LibreOffice, because the European Union payed big money to make Microsoft get MS Office to work with ODT by default.

In short: I don't buy this "I can't read your ODT."
