Owning words?

I am in a bit of a state right now. Not the type of state due to sadness or joy. I am just miffed about how on earth our world is going to go forward. I learned yesterday that a family who's blog I have read with fervor have successfully trademarked several terms or words. These are words that have been used widely in the sustainable living community to describe those of use who live in an urban setting an practice these lifestyle choices. As things stand I can no longer, nor can anyone for that matter, use certain terms to describe our life or home without giving credit to this family for these trademarked terms. I must now call it an urban mini-farm and can no longer be referred to with the terms used to describe it as a homestead. In retaliation today I bought domains with the name "city smallholding" and "city smallhold". I will now call my mini-farm this instead or until someone trademarks that term as well.
