Scott, is your main issue about Landscape being proprietary? Because there are precedents for advertising in other programs shipped with ubuntu, such as rrdtool/mrtg for example. It's the author advertising his site/project/work. In the landscape case, it's also the author of the program (canonical) advertising the site and service. And it's advertising landscape specifically, not the whole portfolio of products and services from the author.
