Remastering and releasing them as two separate EPs IS indeed different from remastering and releasing them as a compilation CD. Releasing them remastered, under their respective album names, is misleading and does not inherently show evidence of a tampered product. It attempts to pass them off as the original demos when they most certainly are not.
"1992-1994 Discography" is more forgivable because it isn't trying to pass itself off as an album of its own, but rather a rereleased collection of songs. It makes blatantly obvious what it is trying to achieve, and the fact that it is obviously tampered with. I still would not buy it unless it was absolutely the only way to track said songs down, but it is more forgivable.
