As inmature I'm my first thought was thst the logo looks like a dick to me. :|
There is another school of thought that is "Always Be Sneaking Dicks Into Your Art". I have some respect for people in the second camp.
But on a serious note the developers should indeed look into this. I recall this comment from HN [0] which highlights why neutral branding and naming are important.
That being said I'm also not really sure what it's supposed to look like anyway (is it an L?) so it's probably worth changing for that as well.
Immature or not, the are at least a reasonable number of people that see just that when they look at the logo.
At the end of the day, is all immaterial, they change it, or they don't, I'm not sure it really matters.
If I'm not mistaken, some designers even go to lengths to make their mundane logos more memorable.
It's not likely I'll be forgetting the name of Loki any time soon so their branding probably (?) succeeded?
They are either going to have to take it off the readme, shrink it, or likely, redesign. Maybe just rotate it 90-120 degrees clockwise.
