Waxy has the story. Sad day for WordPress.
I can’t believe Matt would resort to some underhanded cloaking technique to earn adsense cash. No one would have said anything if he was more open about the whole deal.
Update: Tons of people are flaming WordPress and Matt over this. Lets all wait till he gets back from vacation and hear what he says. This is a big deal though. Imagine if he used WordPress.org to link to a link farm – all sites linking back to WordPress.org (a majority of the wordpress installs) could be banned in Google.
