A simple rule that I follow: I disclose all affiliations when there is a reasonable chance that others might consider it deceptive if I didn't disclose my biases and they were later discovered. In longer format: Sometimes, it isn't even an affiliation with a specific company and I'll simply type something like, 'I admit my bias(es).' For the former an example might be, 'I was an early investor in Tesla and continue to own shares. This may bias my opinions.' Basically, if in doubt, disclose affiliations and biases due to those affiliations. Sometimes affiliations mean the bias is a negative reaction, it's not always a positive response. 'I have previously worked with the Massachusetts Department of Transportation and my opinion may be biased based on those experiences.' If someone could later learn you were affiliated and say, 'Well, that explains their post!' it's probably better to have disclosed the affiliations in the first place. This post is just meant to share how I do it and why I do it. You can, of course, disclose what you want. I think it is customary to make such disclosures on HN. It is in your profile, but I'm not sure many people check profiles.
