+** The Commons and FOSS
+*** Definition (Commons)
+    The *commons* is the cultural and natural resources accessible to all
+    members of a society, including natural materials such as air, water, and a
+    habitable earth. These resources are held in common, not owned privately.
+*** Definition (Software Commons)
+    The *software commons* consists of all computer software which is available
+    at little or no cost and which can be altered and reused with few
+    restrictions. Thus /all open source software and all free software are part
+    of the [software] commons/. […]
+** Software /source code/ is precious human knowledge
+#+INCLUDE: "../../common/modules/source-code-different-short.org::#softwareisdifferent" :only-contents t :minlevel 3
+** But /where/ is this commons?

+*** 
+    - many disparate *development* platforms, with a few dominant players (e.g.,
+      GitHub)
+    - a myriad places where *distribution* may happen
+    - most of them operated by *for-profit* companies
+** Software source code is fragile

+** Takeaways
+*** Software Commons
+- Good news: thanks to FOSS developers we are growing by the day a novel kind
+  of digital commons rich in valuable human knowledge: the *software commons*.
+*** Risk of losing it
+- However: there is a risk of "ruining" it (specifically: losing access to it
+  forever).
+- As per other commons (including traditional material commons, like natural
+  resources), we need to apply *individual care, public policies, and proactive
+  initiatives* to mitigate this risk.
+* Avoiding the Tragedy of the Unmaintained Software Commons

+** Who produces Free/Open Source Software?
+*** 
+- Historically, a community of hobbyists motivated by liberating computer users
+- Today: the above + independent professionals + a lot of for-profit companies,
+  producing FOSS they control in various ways (licensing, governance, etc.)
+- But what is the ratio? We lack /comprehensive/ overviews of the landscape.\\
+  Challenges:

+  - What do you measure? (projects? SLOCs? popularity?)
+  - Free riding is not always visible
+- How much exploitation (of labor) and appropriation (of value) is happening?

+* Outlook
+** Outlook
+*** Takeaways
+- Collectively, free/open source software developers are building a novel form
+  of digital commons: the *software commons*.
+- It benefits society as a *library of technical knowledge* and is exploited by
+  for-profit companies as an *industrial public good*.
+- The *risk of losing access to it* should be countered with /individual care,
+  public policies, and proactive initiatives/.
+*** Open questions / discussion leads
+- *Who is producing* the software commons? (volunteers/employees/civil
+  servants/…)
+- *Who is benefiting* the most from the software commons?
+- Do we need different *public policies* and/or *licensing strategies* to fix
+  any of this?
+- What *other risks* is the software commons facing?
