I've just had my question Was Aeroflot SU2074 intended target in MH17 shooting? closed with reason "This question is about motivations, as such, it's off topic.".
This of course refers to Politics, beliefs and motivations questions should not be allowed here.
However, as far as I can understand, the true motivation (oh irony), behind banning motivation questions is that no one can be certain of individual's motivation. This is however not true in case of "motivation" of larger organization, where decision making is not contained within individual's head. There is communication, leaving possible document trail, intercepts or witnesses.
I'm also not sure if in case of organization "motivation" is the right word to use. In my opinion it that case it would be objectives.
So should questions about "motivation" of (larger) organizations, rather than individuals, be considered off-topic?
