media - SCMP unpublishes an article by Patrick Ho

The South China Morning Post, Hong Kong's leading English language daily, has taken an article by its secretary on home affairs Patrick Ho off its website, writes the Chatter Garden, a new Hong Kong based collective weblog. The article on how the "private sector can bring more creativity" was even pulled from Nexis-Lexis.
"But who? and why? My guess is Patrick received feedback (who?) and took it down.
What surprised me is that SCMP complied. Is this media common practice, take out article from web when the author wishes to unpublish?, asks the Chatter Garden.
Simon World takes another go at the paper for pushing chief secretary Donald Tsang as their favorite for the new chief executive. "Why bother worrying about press freedom when this paper censors itself? he wonders.
