It's a known fact that any lossy compression scheme/algorithm being ITU-T / MPEG Group one or other is developed with listening/watching tests and the involved parameters (transients, high/low frequencies pass/cut-off and so on...) get adjusted on the average best perception results that the group tests gives to developers. All MPEG Codecs were built this way... but claiming that that's enough to tell anyone that a lossy compression format is the same as the lossless original source it's just silly marketing and a lie.
It's just not true, otherwise there would be no need to perform perceptive tests on a group of people to find out the best parameters values when working in the frequency domain, you know...

What a bunch of lies!
