Seems to be worded vaguely enough though, starting at (Prohibited
Uses). Can not Rent; Sell; Lease; Offer on a pay-per-play basis;
Distribute for money or any other consideration; or In any other manner and
through any medium whatsoever commercially exploit or use for any
commercial purpose.

And on

"With the exception of the Educational Use right, you may not
otherwise use the Software, or an portion of the Software, which includes
the Source Code, for commercial gain."

Is Rockbox considered a commercial entity?
