Theory: (Or, Copyleft: Still a   Good Idea!)

1. freedom
2. quality
3. contributions

so why only 10%?

S E C T I O N

Anecdata: There’s More Demand For Copyleft Than You Might Think

SLIDE 20

large companies do not universally hate concept of copyleft

SLIDE 21

specifically, some  like contribution motive for copyleft

SLIDE 22

but no current license works

SLIDE 23

developers are also increasingly frustrated

SLIDE 24

desire for copyleft hasn’t gone away!

SLIDE 25

licenses advance neither freedom nor utility

SLIDE 26

feels solvable

SLIDE 27

feels solvable (if we try)

SLIDE 28

S E C T I O N

Begging: Iterating Towards a Modern Copyleft

SLIDE 29

two vast changes:

1. broad participation
2. death of distribution

SLIDE 30

copyleft must adapt

SLIDE 31

plea: bring back experimentation!

SLIDE 32

legal nerds can help:

SLIDE 33

tweaks? examples: Lesser AGPL, AGPL 3.1

SLIDE 34

different rules for businesses? example: licensezero.com

SLIDE 35

contracts? trusts? example: digitalpublic.io

SLIDE 36

kill attribution  to focus on corresponding source? example: (maybe copyleft-next?)

SLIDE 37

developers can help: accept new experiments

SLIDE 38

please (and thanks!)
