The license fee to be charged in the Linux community is called "guaranteed quality ".

According to foreign media reports, Linux CommunityA letter has been sent to more than 90 Australian enterprises asking them to pay a certain amount of Trademark Usage Fee, saying this is to ensure the quality of Linux products.

According to previous reports, the corresponding enterprise must pay 5000 US dollars to obtain the right to use the Linux trademark. This was once considered a prank because Linux itself is a free software. But in a journal published by the Sydney Morning Herald, Linus Torvalds, the father of Linux, is considering charging license fees. Jon Hall, executive director of Linux International, said a community organization named "Linux Australia" has been appointed to handle Linux trademark authorization, it was the organization that sent a trademark toll letter to Australian enterprises.

Hall said that in the U.S. market, Linux mark Institute (LMS) will handle Linux trademark authorization. It is reported that the Linux trademark authorization will be carried out in other countries, and the specific work will be organized by the Linux community in the country. According to Hall, Linux trademark authorization is not to restrict the use of Linux names, but to ensure the quality of Linux products.
