The following Policies are in effect on AE-BaseApp Sites and Services.
You are permitted to use the marks in publications to identify the product you are talking about, such as "AE-BaseApp Tips and Tricks by Jane Doe." In addition if you write code that uses any of AE-BaseApp API or Features in said publication and you use AE-BaseApp Trademarks you must clearly and in print license such code as Apache License 2.0.
The rationale is that one grey area in most publications is the use of example code. Some publications copyright the code which is against the spirit of Open Source. This is compounded by other publications that license code in different licenses, such as AGPL which is against the spirit of this project. The simple solution is to require all such code be licensed the same as the project using the Trademark.
Lets put it a different way. I have seen books on open source projects, as well as blog posts that license the code such that you must purchase a supplemental license in order to use the code example in anything outside of the example.
This is hypocritical at best, they are writing about an open source project attempting to profit from not only the publication but use of their examples that access the Open Source Projects API's! In some cases they have violated the projects license. In others such as this one it only violates the spirit of the project because of the premiscuous Apache 2.0 License. When Mark Finch conceived of the project he wanted the code to be helpful to everyone. A base application isn't very helpful if you must open your source code. Some projects by their nature should be closed, and with keeping to the App Engine code license Apache 2.0 was the obvious choice.
The issue is the hypocracy in publicly presenting examples in a different license than the original code. The distiction is what you do behind a closed project isn't public, you have in essence created a private fork of the code and modified it to your advantage. Whereas the publication is taking full advantage of the trademarks fame and is using the trademark itself to make money without benefit to the community that worked many hours to build a system that became famous.
