If you are afraid of every critial comment (especially if it is about 2 year old news) then your confidence cannot be really high.
If that company will grow over time and produce good news in the near future, then I will not stop it by pointing out negative facts, it might even help PHUN to better their way of PR.
Explain to me why you as a person that is optimistic about the future of PHUN would like to be in an environment, where everybody shares good news, everybody is telling everybody else what a fantastic company that is and how all of you are becoming rich by holding shares of PHUN.
