I do wonder if it’s legally acceptable to use the name “Ubuntu” as part of a different commercial product’s name - especially after acknowledging on the front page that the name “Ubuntu” has been trademarked by Canonical. Certainly, section 4 of Canonical’s Intellectual Property Rights Policy [0] permits such use only if Canonical were to provide written permission to do so. I presume they want to use the name until a take down notice arrives from Canonical and benefit from the brand till that time? Give that Deepin are a company, I would expect their legal team to either prevent such misuse or to ensure that the written permission is stated on the front page.
