>>It's more like you start a new pizza company and you're not allowed to use Stallman's Pizza Cookbook, which has some recipes you like. You can still hash out the recipes by yourself, with much annoying time and effort (and wasted food). Stallman's just not letting you benefit from his cookbook, because he thinks all pizza should be free.

No, you'd just have to share your recipes whenever you sold the pizza. You can still charge for the pizza (or not) if you want - and the guy who buys it from you can sell it or give it away or whatever.
