There are allegations as well that CCP intentionally did this to drive up the price of PLEX (and in fact, just about every resource in the game)... which has happened. And CCP has colluded with players before to give valuable assets out -- and admitted to this.
Thats an almost slanderous claim, there was one case (5 years ago?) where one employee went "Rogue" and consipered with players for personal benefit, that event caused the company to create an internal investigation unit to make sure it doesnt happen again.
The company involved goes to great lengths to ensure they dont interfere with the games economy without good cause. They have an economist to monitor the health of the economy, and a reserve bank for the rare occasion that the ingame value of PLEX varies too much (i think they have only acted once or twice and there is oversight).
