Hi and welcome to the forum ;-)
- FreeBSD and grub
See How do I configure Grub2 to boot FreeBSD 11.1
- BSD license
Yes, a company can use BSD licensed code, incorporate it in their product and charge for it. But AFAIK that also applies to GNU licensed code ;-)
Several scripts I posted here have a BSD style license.
- Free Windows 10 upgrade
Last March I upgraded my wife's computer from Windows 7 to Windows 10 for free.
AFAIK you still can upgrade for free. See Here's how you can still get a free Windows 10 upgrade
- BSD development
I would recommend to work on OpenBSD.The OS is smaller (important when don't have broadband internet access) and if you are willing to do you homework, the OBSD developer community are quite friendly.
There are several OpenBSD ports that need to be upgraded
You can read about the OpenBSD ports at OpenBSD Porter's Handbook
