In 2006 a "Controversies" section was removed from their Wikipedia page[1] after "a letter of complaint". You can still read it of course[2], part of which is: "Additionally, some both inside and outside the audiophile community have criticized MFSL's [aka MoFi] willingness to stretch its "Original Master Recording" logo. For example, critics note that several MFSL Mk I releases are not from the original masters; one notorious example is the Beatles "Magical Mystery Tour". More troublesome to some, though, is MFSL's recent habit of releasing gold CDs that are sourced from digital master tapes instead of the original analog masters." So it seems these allegations go back quite some time. For what it's worth, I don't really buy in to the whole "audiophile" stuff and am skeptical you can hear the difference, but delivering "B" while it says "A" on the label is essentially defrauding your customers, and possibly illegal (or at least, it ought to be).
