Why would you put privacy respecting in quotes? The subversion of those techniques are probably just because those techniques are so new and people haven't had better technologies yet. I personally consider those privacy respecting data collection techniques as a parallel with the development and use of cryptography on the web. In the beginning pretty much no one online used cryptography; later on we started using them but used weak ones ("export" cipher suites for example, or just look at the issues in early protocols like SSL 2.0 or SSL 3.0); nowadays almost everyone uses strong cryptography. Similarly, in the beginning pretty much no one cared about privacy when they did data collection; then we had begun to care more about privacy, but many schemes are easily broken due to for example misguided ideas of anonymization ("anonymization by hashing"), and we are also starting to see the development of newer private information retrieval schemes and differential privacy, etc. Unlike the cynics on this HN thread, I am quite confident that maybe a decade down the road the majority of data collection done by companies will be in a privacy preserving manner. Of course there will be outliers much like there are still websites that don't use https but those will be few and far between.
