Free Software
From
gnu.org,
Free software is a matter of liberty, not price. To understand the concept, you should think of “free” as in “free speech,” not as in “free beer.”
When I am referring to free software as in free of charge, I may use terms like
"free of charge" or
"free as in price."
Important note: This term is often conflated with the term "open source."
TPM Module
A TPM module is a device that restricts the users ability to use their computer by putting DRM on the hardware level.
DRM
Officially called "Digital Rights Management", but better described as "Digital Restrictions Management" or "Digital Handcuffs" is a way for malicious software developers like Ubisoft or Microsoft to
restrict the users ability to use the software that they create. For example, requiring an internet connection to play a game.
FLOSS
No, not the Fortnite dance. FLOSS refers to Free Libre and Open Source Software. This is a way to remain neutral between the ideas of Free Software and Open Source software.
