+ Currently: on Board of Directors of FSF.

# How These Orgs Relate to GPL?
 

	
 
+ FSF
 
    + Invented copyleft.
 
    + Authors &amp; stewards of the GPL.
 
    + Holder of copyrights on many key GNU programs &hellip;
 
    + &hellip; and therefore enforcers of those copyrights.

# How this Hour Will Go?
 

	
 
+ Materials presented will mix the simple &amp; complex.
 

	
 
+ We cannot possibly cover the entire GPL in one hour.
 

	
 
+ Discuss: motivations, origins, then a few of GPL's sections.
 

	
 
+ I understand the mix of backgrounds in the audience.
 

	
 
# A Restaurant's Lawyer?
 

	
 
+ Considering why you want to learn this.
 

	
 
+ What if your client was a restaurant?
 

	
 
+ What would you want to need to know?
 

	
 
# Restaurant Lawyer: What'd You Study?
 

	
 
+ If you were a restaurant's lawyer:
 

	
 
+ Probably three areas of law you'd focus on:
 
     + building codes.
 
     + health and safety regulations.
 
     + tax regulations.
 

	
 
+ Who would want to hear from?
 

	
 
# Restaurant Lawyer: What'd You Study?
 

	
 
+ Figure out the motivations behind the building code:
 
      + What parts are arcane and less important to inspectors?
 
      + How do inspections work?
 
      + What are the penalties?
 

	
 
+ Figure out the same for health &amp; safety:
 
      + Who inspects, and when?
 
      + What's the health code say, and what checklist do inspectors use?
 

	
 
+ Is there any way the two interrelate?
 

	
 
+ Who is in charge of all this?
 

	
 
+ What was the purpose and intent of these regulations?
 

	
 
# Why Listen To Us?
 

	
 
+ FSF: Understanding the purpose and intent of the GPL.
 

 
    
 
+ Conservancy &amp; FSF:
 
    + both enforce the GPL.
 
    + if your client violates, you will hear from one of us.
 

	
 
+ Such access to drafters, interpreters, enforcers is likely highly unique.
 

	
 
+ Someday, someone in this room may (or already has) sit across the table
 
  from you in negotiations.
 

	
 
+ Our transparency does make your job easier. 
 

	
 
# The Mindset of GPL
 

	
 
+ GPL protects software freedom.
 

	
 
+ Ultimate goal: make sure every user has the four freedoms.
 

	
 
+ Freedom to run the software.
 

	
 
+ Freedom to study and modify the software.
 

	
 
+ Freedom to share the software.
 

	
 
+ Freedom to distribute modified versions.
 

	
 
+ Every clause in GPL was designed to uphold one of these freedoms.
 
     + Or, it's a compromise of drafting in adoption vs. freedom debate.
 

	
 
# Using Copyright
 

	
 
+ GPL is primarily a copyright license.
 

	
 
+ Software is copyrighted.
 

	
 
+ License grants key freedoms.
 

	
 
+ Requirement prohibit activities that take away freedoms.
 

	
 
+ General concept: copyleft.
 

	
 
+ Specific implementation: GPL
