I take issue with point #1, that is true in a lot of cases but not necessarily so, it all depends on what people are willing to accept. While I do agree that the notion of privacy will always lose to technology, and if you believe that privacy is key part of freedom (debatable) then I grant you that point.
1. Counter example: The development of better agriculture freed serfs & at a later time in the US slaves.
2. Modern travel has freed people from oppressive regimes around the world.
3. The internet is having a liberating effect on the freedom and control of information.
4. Modern medicine frees us from the threats of many diseases.
Your definition of freedom, as implied by items 4 & 1, is sloppy and dangerous. The parent posts use the word freedom in the political sense, as an antonym to slavery, subjugation, and tyranny.
Modern medicine raises our standard of living by eliminating disease, which is mostly irrelevant to a discussion of the unique causal effects technology has on freedom.

Technology can be equally used for good and evil.
