Yep. And if Google detects that your page contains a recipe and the microdata isn't perfect, or doesn't include all the things that Google wants so it can show your recipe to people without them clicking through to your site, Google sends you an e-mail through Webmaster Tools telling you to fix it, with the implied threat that your page won't be listed if you don't allow Google to use your work for free.
I'm a little torn with this. On the one hand, it's messed up that Google forces these companies to basically hand over their data, as you put it, but on the other hand, if they don't push companies to do things like this, single-visit webpages like lyrics and recipes inevitably become ad-infested, SEO-driven trash.
Maybe if they used a carrot in addition to the stick, it'd feel less sleezy, but I'm not sure what exactly that would look like.

The opposite may also be true. If Google sent visitors to these sites instead of displaying their content without compensation, the sites wouldn't be so desperate to extract every last penny out of the reduced number of people who click through to them.
