"What makes me angry about the AdBlock plugin is that the author – while happy to destroy our revenue stream – is also profiteering from the very same free content model by asking for PayPal donations when the plugin is installed. Talk about hypocrisy."

  What an idiotic comparison. The adblock author is directly asking money (voluntary donations actually) for something useful he made for your use. Straightforward quid-pro-quo. You know... commerce. What the hell is wrong with that ?
