We are having a discussion over on Stack Overflow about whether or not people representing a commercial product can answer their own questions about their own product.
To make it more concrete, just take a look at the discussion I'm referring to: Why Does FDT 5.5 Not Find My Flex SDKs?
The OP refers to this article which seems to ackowledge that he can do so: https://blog.stackoverflow.com/2012/05/encyclopedia-stack-exchange/
This article states that you can just answer a question of your own (even if you already know the answer to it up front). However, it does not mention anything about commercial products or the people representing it.
Should they be allowed to do this?
As I already mentioned in the discussion on Stack Overflow, I think the OP's Q&A is valid because it probably answers a question the product's users come up with quite often and it makes the information more findable. But it's a thin line: where does a helpful Q&A end and where does shameless self-promotion start? This is of course just my opinion; I'd like to hear yours.
