On another thread, I read we can not opt out of this WP deal, is it true?

Hey Madelaide,

For the Crestock plugin, you have to opt in, which implies you're opted out by default.

For the "Microstock Photo Plugin for Wordpress" which currently uses Fotolia photos, there's no reason to have an opt out as the plugin enables bloggers to 'buy' images. As contributors, this plugin just helps Fotolia (and very soon other agencies as well) to sell more photos. The bloggers get the ability to activate referral links on the images they use, but that doesn't directly affect us as contributors (though it has the potential to drive buyers to the agencies enabled through the plugin).

Isn't that exciting?
