I was trying to find the last time I commented on this story (wasn't sure if it was done here or elsewhere). I remember reading an article a few years prior to the Bloomberg story where Apple had talked about photographing their server components as part of their supply chain security. Someone replied that the article could have fit Bloomberg's timeline of events and could have been a reaction specifically to what Bloomberg had been reporting on. I see the talk you linked is from Feb 2019. I'd be curious to hear about interest or measures taken prior to Bloomberg's timeline.
