I've come across several answers within a particular tag in which an answerer will recommend a specific product that is made by the company for whom the user works. The answerer does not mention their association with the company. The product addresses a rather niche segment of the developer community. The asker is not asking about the product in particular; the exchange is more of the form:
Q: I want to do Foo.
A: Bar can do Foo for you.
To be fair, the answerer often provides a reasonably detailed explanation of how the product can address the problem.
How does this community feel about these kind of answers? Are they acceptable, or should they be flagged?
