I wonder... if the UNIX copyrights are of any good to damage Linux or Open Source, why would have other big companies involved in and benefiting from Linux and Open Source taken any risks by allowing for these assets to end up in unfriendly hands? On the other hand, if the UNIX copyrights can potentially be harmful when misused, what would a.o. IBM and Google have for an apology for letting it happen?
This is of course under the assumption that the "certain intellectual property assets" did contain Novell's UNIX related IP...
