Actually I think Amal is being very reasonable and reserved about the matter. I would be much more pissed than he is after all the rigamarole he’s went though. In my opinion, the reality is that the vast majority of people have no idea how payment schemes work, or any desire to learn. These people will not read through these technical posts or the constellation of background information that is required to understand them, so no PR harm on that front. The people in the know who work for this payment system don’t care about these posts personally, either.
The only people who care are us exceedingly small subset of the population that knows a bit and wants to know more, and posting background information like this is invaluable for us. Biohackers have never thrived by hiding things from each other, and Amal is definitely a no-nonsense type of guy when it comes to advancing humanity.
