Someone will turn it into something
After reading the article and looking at the logo, I can see what people are referring to but if I had not looked at the logo, I would not have seen the "sex act".
When my wife and I were thinking of names for our sons, we started avoiding certain names because of how kids might twist them into something else as an insult. After a while, we came to the conclusion that no matter what name we gave our sons, if another child wants to insult them and can't turn their name into something else insulting, they will just use a generic insult.
The same could be said about this logo: somewhere, someone is going to see something in any or image. The committee should just avoid obvious images and recommend their logo based on their best efforts.
