I am not saying whether you should or should not use this product. My point is that before using such products, you need to read really carefully where and how you can use it this product because of the included resources or intended purpose for using this. It is not sufficient to only read the README file and decide based on that.

The key part here is the second sentence "Use of these trademarks or logos must follow Microsoft’s Trademark & Brand Guidelines.". But there can be other such limitations also, just hidden somewhere else.
