You're casting aspersions on not just a single person here, but a team of developers who have been working on this together. Your criticisms are also so utterly lacking in detail that the person on the other end can't possibly defend themselves in any meaningful way. What are they going to do, tell you that they actually have a great track record? Also, sullying the reputation of a developer while hiding behind an alias is pretty low. Whether the criticisms are true or not is irrelevant, of course.
