> Your first sentence is a little confusing, but I can confirm that Google, at least, uses lots of open source software, and the build system automatically checks that all the third-party libraries used in an executable have a suitable license.

That is, "higher-end commecial users would actually check the license, and are not engaging in this kind of behavior; lower-scale commercial users don't care about the license, and are engaging in this kind of behavior."
