I think the reason stated in the topic was rather concise and left no place for interpretation
There also was a clear consensus amongst the staff about the decision, what we've seen since install base started (and even before on resetera) made it pretty clear that this topic wouldn't end well in all likelihood, brings a ton of concern from both staff and readers and just be a time sink in term of proper moderation involvement all for the purpose of a thread whose added value wouldn't be worth it to top it off.
What we've known about the project is a title screen and Enix strategy regarding DQ the past few years, if the poll is all that matters to you then by all means I think you're free to create one and share the link in the M-C/Square-Enix thread or other appropriate topics.
As far as discussion is concerned
oseki summed it up yesterday rather well, and I assume most regular probably understood it that way as well
(As usual in this thread this a post about sharing personal opinion, other mods/staff take on the matter may vary)
