The topic that Yosuke posted says that the releases are licensed from the labels that own the recordings. If that is accurate, they're not bootlegs by any definition. It would be easy to contact the labels and ask them if the reissues are actually licensed from them, but I don't care about Judas Iscariot and won't be looking into it because I'm not buying the albums.
This is almost as dumb as Wrest claiming that Moribund illegally licensed Leviathan recordings that they proved that they legally own. He even said that he doesn't get paid residuals, which was also proven to be a lie. It was also proven that he tried to extort money from Back on Black by threatening them, which is ridiculous.
While it totally sucks that a lot of record labels own the music that they put out, nobody makes the artist sign the contract without negotiating the terms.
