I don't see how you can blame a 'searcher company' for lack of response to what seem to be your birth father's family- or am I reading your original post incorrectly and it's another issue that is the problem?
I was contacted by a close DNA match a few years ago. The situation is more complex than they realise. I did explain that I couldn't help them because it would hurt several innocent people but the other factor was the information I found when checking the details of the match's father.
I think you make a fair comment & it's why I am loathe to name the agency. And not hurting others is also paramount & I did mention the man's wife might still be alive hence no response.
