In these cases, I think that it is always best to suggest to the user to
install rather than have a programme install it for you without your
permission. The user should always be in charge.Are you on a Windows box?
I don't understand the "permission" aspect of having LibreOffice install
fonts automatically. If a user is voluntarily installing the program, then
they should accept whatever modifications the program performs. If would be
one thing if LibreOffice was installing a virus--it's simply installing
fonts which provide for a better user experience. It seems like it would
make sense for it to install free, open source fonts, especially if the
documentation is going to use a font other users may not have. We use
OpenOffice exclusively in my organization, and I can honestly tell you not a
single computer (300 of them) has the Liberation fonts installed. If I
wanted to distribute the documentation guide to my coworkers, they would not
be able to view it in its entirety.
And yes, I use Windows exclusively.
