These questions can certainly be interesting, but I'm not sure they fit into the SE model. They can't be answered (well, not unless a representative of the organization actually posts a response), and they invite speculation. There could be a whole host of reasons underpinning a particular design decision, not all of which are related to human factors, so not only is it impossible to choose a correct answer, but many of these answers could end up talking about topics unrelated to UX.
What do we do about these topics? Do we -
- Leave them be - they provide scope for interesting and engaging discussion, which is good enough for us?
- Edit them to ask what human factors reasons might have underpinned a design decision, and which were most likely?
- Close such questions as off-topic?
