The Mozilla Manifesto Addendum

Pledge for a Healthy Internet

The open, global internet is the most powerful communication and collaboration resource we have ever seen.
|
||
It embodies some of our deepest hopes for human progress.
|
||
It enables new opportunities for learning, building a sense of shared humanity, and solving the pressing problems
|
||
facing people everywhere.
|
||
|
||
Over the last decade we have seen this promise fulfilled in many ways.
|
||
We have also seen the power of the internet used to magnify divisiveness,
|
||
incite violence, promote hatred, and intentionally manipulate fact and reality.
|
||
We have learned that we should more explicitly set out our aspirations for the human experience of the internet.
|
||
We do so now.
