Remember, the development of bitcoin will be based on the people who are using it. We shouldn't make the reputation of bitcoin bad just because of our personal interest.
I will just quote the last part since I think this is an important one.
Personal interest. Don't we see it already with scam ICO's. If not personal then a team bad intention to just make money out of nothing.
They use bitcoin and Ethereum as means of payment to avoid tracks.
Although there is still a way.
It is not that different with donations since they are just using the offering word in exchange for their tokens.
We will see more of it once there is a news that bitcoin will grow again after the halving. News which are backed up by facts.
