Is it ok to use SO to push a (open source) product for which you are offering (commercial) support? By pushing I mean mentioning your product and how it is doing "better" than concurrent products in every possible answer (note that I'm not affiliated to any of them).
Some answers/comments to illustrate this:
Is this Astroturfing? Is this allowed?
Edit: Thanks for your answers so far. I realize there are similar questions on Meta but I find it hard to extract any official consensus from all answers (which are in my opinion sometimes giving opposite or divergent points of view).
For example, I tend to find the answer given in the second example above irrelevant (the question is about product X so why answering "my product Y supports this") - which is actually why I opened this question on meta.
So I'll keep this question open a bit to gather (maybe) more opinions/feedback.
