No. CC has issues with their bitmaps, but these are just a distrbution issue. Any map created with CC is your own creation, just like any story written on a word processor is your own story. The only things they've said is you can't create a CC2 map that's just a means of distributing their symbols (real maps containing their symbols are fine) and you can't distribute the CC3 bitmaps in any way. This means that people have to own CC3 to see your maps, but there SHOULD be a viewer coming with encrypted bitmap packs so that you can view and print CC3 maps without owning the program.
Heck, they let me sell symbols to work with their program with little or no hassle at all (and the hassle that's there is COMPLETELY justified, I sought out some of it on my own because I wanted to be above board.)
I'll put the sketch maps on my todo list. They'll probably only take about an hour, now that I know they don't need to look professional.
