I am not disputing that it's a well-engineered piece of technology. It may even be superior.
That's irrelevant.
I expect a level of professionalism and ethical behavior from an open-source project, especially if I rely on it pretty heavily. Placing communist imagery in the logo isn't amusing. And no Russian would find it amusing. I certainly don't. I prefer that my software not make any political statements. Especially if the system it purports to support is responsible for the death of millions of people.
