Personally, I think it is a more varied and nuanced issue than whether it says 'Open Market' or not. Just me though. If it says 'Open Market' that doesn't mean the company WILL sell to anyone at any time without refusal or the controller saying so. It just means it CAN be treated as such. To assume that because I want anyone to be ABLE to buy it, so I label it 'Open Market' and yet can't tell someone 'No' with my work is ludicrous. If that is the case, why bother to punish plagiarism in the Factory? Because they don't need to copy and paste my sub, they can just pick whatever they want without my say so anyway, just because I didn't want to pick a Faction/Group specific designation.
'Open Market' doesn't mean anyone for any reason. Nor does even saying 'Faction Specific - Mandalorians/Jedi Order/Whatever' mean anyone that meets that criteria can have it no matter what. It is merely a target audience. Nothing more, nothing less. People outside it may very well utilize it. And people inside it may not, or may be denied it. And even people you want to not use it can have shell players or allies of theirs obtain it and then trade if off to them to work around things.
'Open Market' It is a base parameter, a marketing demographic if you will, and nothing more. I have never interpreted it as a blanket permission statement, and never will. Nor are any of the products any of my characters or their companies make or sell marketed/made in such views. I spend the time to write the sub, sit through the judgement process, etc.... Then the least you as a writer can do is PM me for permission.. Or Skype... Or respond to my Marketplace... Or even try a thread to contract for it if we're talking more than a personal number of items. Even if it is 'Hey, I know Item X is for Faction Y but I want my guy in Faction Z to have it' I guarantee you I will listen to your idea as to how, and if you come to me with a viable plot to obtain it, I will go to the lengths needed to help make it work ICly.
The main thing here this rule is emphasizing is what MANY rules here state when you boil them down to base, and I think it is silly we have to do addendums and discussion on it/them as they are stupid simple, and it is simply thus: Don't be a dick.
