Yes, but 1) it's unnecessary conjecture when the facts already make them look bad, and 2) it's not the limit of what they could actually do - their TOS says (IIRC) "as long as it's for the purpose of improving our software, we can use anything you make". So they could use peoples' drawn art directly, for splash screens, or even, (speculation) offer it as a template/stock material for anyone who pays them for it.
