The curious case of Patrick Yeoh Not Teoh...Niamaaah

Folks, meet Mr Patrick Yeoh Eng Kong. Mr Yeoh says he is a shareholder activists. Mr Yeoh is a minority shareholder in CN Asia Bhd.
The top guns of CN Asia says there have n o clue what Mr Yeoh is up to. The Edge mentions greenmail.. but everyone who is anyone in that article says they never heard of such things.
Oh by the way, the shareholder activists was suspended as director of SCAN Associates for serious breach of duty.
Can any one explain what it means. Looks like there are too many sides to Mr Yeoh 's face, depending on who is doing the painting.
Let's just hope : This is NOT a case of Harap kan Pagar. Pagar makan PADI.
