I am really new on steemit so I might not be grasping fully the issue debated here.

It seems to me that everyone can advertise and promote their stuff. If someone has an issue with other persons project they are right to criticise and point out flaws. We should all be prepared to receive constructive criticism. The person running the project should be able to answer the questions in a manner that clears the doubt. If they can not do it then its their loss.

Of course, often people follow those who shout louder and not those who put forward well reasoned arguments. We could end up ostracising someone who did not deserve it. Being wrong, making a mistake is always a risk. As long as we are equally ready to come forward, admit such a mistake, apologise and make up for it we should be fine.
