nice drawing effect but the copyright claims are pretty dangerous: they claim any art created with it must have a creative commons attribution license. this is total BS.

They should probably make this more obvious but other than that, I fail to see how it is total BS. If you don't like their licensing terms, don't use the product...

It's not like stuff made with the GCC has to be GPL. I'm not even sure they can enforce this.

Their licensing terms are dubious. You're using their tools to make original art.
