Most folks outside of technology fields and the software freedom
movement can't grok why I'm not on Facebook. Facebook's marketing has
reached most of the USA's non-technical Internet users. On the upside,
Facebook gave the masses access to something akin to blogging. But, as
with most technology controlled by for-profit companies, Facebook is
proprietary software. Facebook, as a software application, is written
in a mix of server-side software that no one besides Facebook
employees can study, modify and share. On the client-side, Facebook is
an obfuscated, proprietary software Javascript application, which is
distributed to the user's browser when they access facebook.com. Thus,
in my view, using Facebook is no different than installing a proprietary
binary program on my GNU/Linux desktop.
