In response to this answer question I commented that:
When you work for the company that makes the product, it is normal practice to explicitly include a disclosure at the beginning or the end of the post (even though it is in your profile and you imply it by the use of "we")
Ira Baxter (the answerer), replied
It is official Stack Overflow policy that the phrase "Our" ... is adequate disclosure. That was resolved many years ago.
They are correct, in that the use of Our was established in a Meta-post many years ago.
I would assert that this define the default stance for all sites on the stack exchange network, but that we are fine to establish higher and more stringent requirements for this site.
I think we should do so. Given that Recommendations are off-topic for most sites in the network (and I think were off-topic on all sites when that policy was created.), but are on-topic here, the scope for the amount of promotions is much higher. Thus to match, that our requirement for disclosure should be much higher.
I suggest that implicit disclosure, via the use of world like "we" and "our", should not be considered sufficient. And that instead a sentence stating with the bolded word Disclosure: and going on to say the appropriate detail, at the beginning or end of the post, be required.
Don't get me wrong, answers from people who made the tools are not bad answers. They are probably some of the best people we can have answering: they know there tools better than anyone. And yes, biases exist that are not from employment (just think of any tech where somone can be described as an X-Fanboy)
But I think the reader would really like to know at a glance, if a post comes from someone who was involved (financially and/or developmentally) with the product in the answer. And I think the best way to do that, is to have very clear and very explict disclosures in such answers.
