Translating into IT / tech terms, people are VERY used to the concept of two .wav files sampled from the same CDrom being bit identical and useful in a court of law to prove both .wav files came from exactly the same music cd. However people are really worked up about a new online service that encodes multiple analog music sources into lossy mp3 samples using different analog encoders each time, and the service sells an "identify matches similar to this song" as a service that people think is the same level of exactness as the old fashioned court-of-law .wav file bit by bit comparisons, but its actually more of a lossy best guess pattern matching service instead. Yes they DO use the same general technology, mostly, but its quite different in purpose and outcome. An even better analogy is we are VERY used to an online service that OCRs a scan of a music CD and outputs the musician name every time based on OCR of the disc itself, and now people familiar with that technology are VERY confused by an app that listens to your cell phone mic and often squirts out the musician name based on that raw analog sound sample. Its more a miracle the new tech works at all, than a scandal that both business models aren't identical in accuracy.
