Today was an Action Day by a Facebook group called "Take Back Urban Homesteading." I'm not clear on all the details, but I'll try to summarize the basics in order to raise general awareness.
Evidently, there is a homesteading family in California that has somehow copyrighted or trademarked the phrase "urban homestead." Any person, group, organization, blog or website using the words "urban homestead" for their own project will soon get a letter threatening legal action. This has caused a surge of outrage against the California family. It's certainly not working in their favor; they have alienated many of their friends and clients associated with their various businesses related to urban homesteading.
Homesteading has been part of American culture for a couple centuries. For some families, it's not a business, it's a way of life. It's certainly not a copyright. It's astonishing that one family thinks that they own a concept so old, and it's shameful that they try to trademark the phrase for their own profit. Good grief.
