USB2.0 EH with USB type-C in accordance with USB specifications? Reasoning?
Type-C is a connector specification, and a set of means/rules how it can be useful. The Type-C specification has nothing to do with OTG, in fact, there is not a single mention of OTG in the entire document. Type-C doesn't have the ID pin, and therefore none of OTG methods are applicable. Type-C doesn't "superseeds" OTG, it replaces it entirely.

In place of awkward OTG, micro-AB, session control and other baloney which no-one ever used, Type-C offers a simple and clean model of Port Role switch using CC pins. The Type-C connector doesn't enforce the use of SuperSpeed, it is perfectly legal to have only the USB2.0 signal portion implemented.

Regarding the use of copyrighted artwork. You can't just use the USB artwork. To have a right to use it, your product must pass USB-IF rigorous certification process. To get it done, you must join the USB alliance, and therefore execute the adopters agreement, and then run your device through a certified Lab. Unfortunately, there is no mechanism to enforce this process, so many OEMs either put the artwork illegally, or ignore/skip the entire certification process.
