Web founder Berners-Lee makes the argument that certain information should be available universally. He made his points at the world economic forum in Davos. Berners-Lee said that information is in silos. You are unable for example to share images in one Social Media account with another. This is even though the pictures are yours.
In addition, accessing and disseminating information that should be public is often criminal with severe legal consequences. Laws are not keeping up with technology.
Accessing and sharing certain information can help society in general. This may include public health issues and infrastructure data. The argument goes that having this information in the public domain can help bring about solutions. It does exclude information that revolves around national security and similar.
With Aaron Swartz, some feel that the government overreached. The prosecution threatened a 35-year jail sentence and $1M in fines. Aaron Swartz committed suicide.
