Thanks for taking an interest in FreedomBox!
I’ll be honest: it is extremely unlikely that we will change our logo. Our current logo was designed by @mray and has been in use for years. The butterfly logo has become the core, identifying feature of the FreedomBox brand: that image is now associated with a set of ideas and an entire software system. We wouldn’t want to undo the years of work it took to create that association between image and idea. On top of that, I think everyone on our team is very happy with the logo as it is.
There may be other, more productive ways for you to contribute to our community. If you want to get involved with design matters in particular, then @mray is the best person to talk to.
