They were definitely tools available to all of us that allowed this type of access to personal data and more. Specifically a lot of the lists that were generated about who to follow suggestions were manually curated at the time and we could put whoever we wanted on the list. We were expected to put people that were relevant in our industry on those lists, but I think Ahmed actually got in trouble for putting himself on that list to build up his Twitter following.
At the time it was certainly a major initiative to rebuild the legacy systems to fix exactly this type of problem. There were strong mandates from the top of the company that were made abundantly clear to us that while they were fixing these things we were all under agreement and NDA to keep all of this data private. The systems were broken no question, but the message was clear. That just makes it even more disappointing to see what he did. He has a very young family at home that is now going to be totally broken.
