history of software freedom
in the beginning, all users were free
computers [examples?] came with software
software source code was shared freely
companies saw no reason to lock it away or forbid sharing and modification
something about hackers and the MIT model railroad club?
proprietarization
mostly through the 1970s
IBM in 1969[?]
copyright extended to software
"Open Letter to Hobbyists"
GNU
FSF
EULAs
legally-binding contracts
began as a way to limit warranties and disclaim liability
in the mid 1980s, became popular in forbidding sharing and modification
Linux
open source, Netscape
something on DRM maybe?
modern EULAs
limit free speech
allow developer to change software remotely without notice
to add:
FSF
FSD
Linux
open source, Netscape
importance of software freedom
car analogy, welded hood
"code is law"
restrictions
limitations of freedom 0
software obeys developer, controls user
trial versions with limited features or time bombs
screen shots in MS Windows Media Player
printing DRM-enabled PDF files in Adobe Reader
features of MS Windows locked away in "Home" editions
backdoors and tracking
list of all installed software sent to MSFT on Windows update
NSAKEY
Nintendo 3DS logs
Amazon.com Inc. deleting books from Kindle libraries
Apple iPhone location tracking file
reliability and security
prop. sw: only developers can audit
free sw: anyone can audit
security through obscurity: only devs can find security holes
thoroughly disproven
studies
crackers find holes anyway
but users can't fix holes themselves
ex: HTTP Range header bug
bug in HTTP, affected all Web servers
solutions discussed on Apache list
Debian maintainers (Apache users) added patch to package
Debian released a complete fix 9 days before Apache did
proprietary software kills people!
commercial free software
many believe that money can't be made in open source and free software
logical fallacy, false exclusionary disjunct
if a license said that software can't be offered for a price
it would be non-free
