"In short – if you want to start a company or website related to Blender services, avoid using the name Blender in it. You can use it as a secondary tagline though – such as “Awesome Company Inc., the Blender specialists”. Same goes for forks of the Blender software, give it a new name and create a unique brand that way. The latter is also enforced by the GNU GPL, which explicitly excludes brand names from the freedom."
