This seems to be misread; as the messages condoned to this matter are explicitly clear. Let me clarify;

specifically referring to commercial purposes; this would allow donations to be accepted to individuals towards their values and cause, not to the product itself.
The moment they start soliciting for donations, do anything for profit or launch funding campaigns, etc. it treads a very fine line on what is already a sticky legal situation - if people want to approach them voluntarily to donate that is another thing entirely.
Regardless of anything like above the moment there is any potential profit making involved it significantly changes the scope and chances of legal action being taken.
