I act for Linus Torvalds, and I am writing to you about your use of the trade mark "Linux". This is not a letter of demand, but rather a request for your assistance, and an attempt to inform or remind you of the rights and obligations associated with the use of the trade mark "Linux".
My client is the owner of the trade mark "Linux", which is a registered trade mark in the United States and various other countries, and currently an unregistered (or "common law") trade mark in Australia.

Looks like it's free as long as Linus is happy, otherwise no better than Unix. You pay lots of money to call your OS a version of Unix, looks like profiteering to me
