I think that this kind of commentary is fair to the topic of any product that has competitors (and if they are similar or sharing code), and very well and seemingly fairly presented by RickDeckard.. as usual RD provides sources for his assertion and seems to describe what is going on in a mostly reasonable way - even if some of it might be tied to his opinion, too.

One of the matters regarding the creation of an "official thread" should have been to create this thread as "Self-Moderated," and so it seems that OP had made the mistake of not making this thread self-moderated (which I believe cannot be changed after the thread has been started as not self-moderated), but OP could make a new self-moderated thread if he believes that some of the criticisms and/or drama might be going too far, too distracting and taking away from the topic overall (or maybe his preference to promote the product without having some potentially heavy hitting contrary statements....and if he would like to have a more clean thread that he is able to control any kind of controversial commentary that might come into the thread, then he would likely need to create a new self-moderated thread (unless there is a way to change it to self-moderated after it had already been created, which I doubt.. I think that the forum does not like to change threads in the self-moderated kind of a way after they have already been started). 

Surely, I had heard some of the accusations that Foundation had stole the code from the cold card, and whether those are fair-game criticisms may well be taken into account in any thread that is not self-moderated...so long as there are attempts to otherwise stay topical.. and whether or not personalities might be relevant to the conversation, too.
