FB ads engineer here. Every time I read these threads, I'm 1. Flattered by how sophisticated HN thinks our systems are (they're not. and we're not that smart. FB's A-team stopped working on ads a long time ago) 2. Entertained by how HN thinks ad targeting works (we don't want to know everything about YOU. we want to know basic info about all of our users.) Hypertargeting doesn't work. Targeting small audiences doesn'…

You seriously believe that the encrypted communications platform that the US government desperately wants a backdoor in is secretly backdoored by Facebook for ads? Something that mundane?
The platform (WhatsApp) that is subject to huge public skepticism, who's source code is so limited in scope that it's probably been audited by every security researcher that is interested in posting a "I found Facebook being evil" blog post?
And you believe they are using this data for ads? The most obvious thing ever to see if you audit/monitor the app?
This is why theories like this borderline paranoia. FUD. Nothing more. Statements like that discredit your entire argument.
-- And yes, of course Facebook uses trackers on sites to figure out what sites you've been to. Of course they use unencrypted data available to them to target ads. Your data is already in their database. Just because it's in another table to allow the "big bad ad agencies" to target you (data the ad agencies can not even see) does not make it any different.
Everyone does this. Everyone will continue doing this. There is absolutely nothing morally wrong with that status quo. The only part that can be morally wrong, is if a human themselves inspects the database without respect for privacy.
And this is why we have laws for dealing with malicious employees, robberies, house break-ins, etc. Things happen whether it's online or offline. All of this was possible (arguably even more so) before Facebook. It's just more centralized now.
This paranoia simply needs to stop.
EDIT: Adding, it makes complete sense that Facebook's A-team is not working on ads. Taking a page from Google: Diversification. Ads are auto-pilot income, have hit their tech ceiling, and Facebook's longevity depends on investment outside of their core business. I am unaware how this is so unbelievable to some.
