You’re getting Unix and Posix confused now. Unix and Linux both conform to Posix standards, but doesn’t mean they are the same family of operating systems, they are clear and distinct subsets within the Posix family.
And while the current owners of the Unix trademark possibly would be willing to prostitute it out to a foreign clone like Linux for a few pieces of gold, they haven’t yet nor do they have any plans to, so once again you’re just trying to muddy the waters rather than admit Unix is the American original and Linux is the foreign clone, but facts are facts and you’ll have to live with them.
UNIX certification is not POSIX. POSIX describes an application portability interface. UNIX certification describes the system calls, libraries, utilities, C language and interfaces of an operating system. Learn first, talk later.

It doesn't work that way, there's nothing to plan, and they really have no choice under the system they created. Any organization can make its operating system UNIX compliant and then upon application and testing the Open Group will certify it. There's no "prostituting" on a system based solely on merit. You are still thinking emotionally. You and open source zealots are the only types I know who do that.
Unix is the American original and Linux is the foreign clone
I never said UNIX wasn't an American original. Everything else, including BSD, is a clone. Or you can agree with Dennis Ritchie (a creator of the original Bell Labs UNIX) in that all UNIX-like systems are de-facto UNIX (looks like a duck, walks like a duck...).
Given your hatred of all things ripped-off, remember that UNIX was ripped-off from Multics. Multics was led by MIT and Bell went in on it. Ritchie and Thompson took all their knowledge from working on it and started UNIX at Bell, after which Bell abandoned the Multics project. If you applied your hatred equally, you should be railing against UNIX and Bell.
And do remember in your love for lawsuits to hurt open source, that the only reason Linux exists is because of the lawsuit against BSD by the owners of the original UNIX. Torvalds has said he wouldn't have bothered with Linux if BSD had been available, and the only reason it wasn't available at that time was the lawsuit.
