Doxxing on HN feels like it should have an extremely good reason to do so, IMHO. Unless you are 100% sure you are correct, all speculation should be avoided since you could cause severe damage to others by misattribution.

From reading other posts by Ryan, he seems to be trying to talk about the general problems he faced that simply don’t get surfaced often (for example, due to the associated risks to your career.) He provides enough detail to help anyone likely to be in the know to identify the person.

There is a very difficult balance to make, and he has clearly been careful about judging that balance, and getting feedback from others on that balance.
