Teddy was referring to the master recordings of his tracks for Invincible. At that point, recording had gone on for nearly four years and Mottola was getting fed up with mounting costs, and he was demanding that producers and engineers turn it all over. The same thing happened during the recording of Dangerous — Teddy was told, “No more delays. Do not record one more song.”
As for his Killer Thriller speech, as SmoothGangsta said, MJ referred to an unnamed compilation album. It sounds a lot more akin to Number Ones than The Ultimate Collection.
MJ’s personal image was already widely damaged due to the events of 1993 onward; I can’t imagine he was too concerned with what the tabloids said, given that they’d twist anything against him. His catalog was another thing entirely. I don’t believe for one second that he’d purposefully release a low quality album to “stick it to Sony,” especially since Invincible was his fastest-selling album worldwide since Dangerous before all promotion was pulled.
Again, you’re pulling things out of thin air and changing the context of quotes to fit a narrative you’ve created. As is tradition.
