Actually agree with you about it, perhaps the No-Derivatives is better then. But then the license makes it harder for others to improve the logo and continue working on it.
If Speeduino is to be associated with the “S” wagon logo is the last thing you want someone forks the project and the logo design. Although it is unlikely but there’s legally possible.
From what I understand the only real protection against it is brand protection witch is another thing. Then companies can’t use similar logos. Even with a more stricter cc license like (CC BY-ND 4.0) there is still the possibility of building a new logo that is similar from scratch. But with no derives license nobody can’t just take a copy off the logo, change a little bit and use it without permission from the creator/creator’s witch might be a great thing. But lets hear what Josh and others thinks about the S-wagon/ long hood Dodge wiper design type of logo and the type of licensing.
