I personally have no opinion either way. I will add in a few comments though:

If it is a legal issue, we should change the artwork and branding. I'm
not too familiar with the Creative Commons licenses, but if they
prevent us from reusing the artwork and KDE e.V. decides to kick us,
we'll need to replace it regardless, so it would be wise to have stuff
ready regardless.

When most people think of rebranding, they think of both the names of
the apps and the artwork, or at least most of the people I know
(myself included). If it is just the artwork, we should say "artwork
rebranding" instead of just "rebranding".

For the artwork, I can go around with my camera and take pics of some
of the scenary in my area. While I don't particularly like the scenary
here, a lot of people do. I personally don't care for a bunch of tall,
lighted buildings in a blur of smog, but apparently that is popular
(I've heard so many people say, "Ooh, that is so pretty!" when driving
into town at night). Buildings aren't the only pics I can get. While
it's too late to get a snow covered landscape (spring finally arrived
after weeks of unpredictable weather), I can get some spring and
summer stuff, and maybe autumn if we're still working on the artwork.
I'm no good with photo editing and imposing pics and logos on top of
other images, so someone else would have to do it, but I can still
send some stuff in.
