  - By default, works are have All Rights Reserved
    - Until big corpo and/or pirates get their mitts on it
  - There’s two big classes of license
   - Permissive
   - Restrictive
  - Can also control other things
    - Some licenses have ethics clauses
    - Some are royalty-free

  Q: First up, what is a license?

  A: A miserable block of text, next question

  - Copyright law is a bitch, Posting your stuff online is a bitch

   - Basically a license is your way of telling other people what they can and can’t do with your stuff

   - By default, your stuff is under All Rights Reserved, which means you own it and if anyone wants to use it/look at it/share it/what have you, then they’ve gotta go through you first

    - In practice, that's probably not gonna stop anyone until you get lawyers involved

   - So with the kind of licenses you can get off the shelf, there’s two main types, Permissive and Restrictive, I find it helpful to think of these from the point of view of big corpo
  - Permissive: Basically gives downstream people more freedom to do whatever they want. Like making their own copy of your stuff and selling it
    - Big companies will generally only use dependencies if they’re under a permissive license
  - Restrictive: Intended to protect specific freedoms, like distribution and modification
  - Licenses can attempt to enforce other things like ethics clauses or royalty free
    - Royalties in this case are basically a subscription fee to use a copyrighted work

  - As outlined by the Stall Man himself, this outlines what’s open source or not
  0. The freedom to run the program to for whatever and whyever

  3. The freedom to do that with your modified versions

  - #link("https://interoperable-europe.ec.europa.eu/collection/eupl/solution/licensing-assistant/find-and-compare-software-licenses")[EU Licensing Assistant] makes it easier to compare licenses in my opinion
  - #link("https://spdx.org/licenses/")[SPDX] is gonna be the most thorough source, has a list of like every license on earth, and licenses are typically identified using their entry in the SPDX list
