Saying we’re going to do “ traffic monitoring” doesn’t carry the weight of “we are going to listen to your private conversations”.
I'd wager that most participants don't know the full details of the program, but "company pays you for your usage information" is a very old thing. You could (maybe you still can) get paid to install a box on your TV that recorded all of your viewing statistics to be used for market research.
To me, the biggest concern is that this is only really viable because Facebook had nontrivial market penetration of a more-or-less unrelated product to their main offering. This isn't something that Snapchat could have easily done to get market research on Facebook usage, for example. This feels (to me) more like an anticompetition concern rather than a privacy concern.
If Facebook wanted to learn the protocol Snapchat uses, they only needed a single test device. If they only needed to learn usage patterns, they could’ve checked where the traffic is sent to or app usage time etc.
Installing a root certificate is very intrusive and they behavior shows that if they are ever given the opportunity to be become a root certificate authority, they are likely to issue malicious certificates. As far as I know, no website can pin their certificates, so this takes us back to pre-HTTPS days where ISPs and network operators had a lot of fun reading user traffic.
Those boxes have been phased out in favour of “Personal People Meters”[0], which are basically a pager with a SIM card that you wear which has a microphone listening 24/7 for TV broadcasts. You must keep it on you, listening at all times.
Nielsen will pay you $250/year (less than a dollar a day) for the data you provide.
Now, Meta decides to MITM the communications that I intentionally encrypted so that it can gain a competitive advantage…well, remember when meta kicked out researchers what had obtained consent from users to perform research on its platform? That was not even illegal. This is.
The whole thing's a mess, but it's funny to me that people would get indignant over a user letting another party intercept analytics data. "Hey, that's my data from spyware! Get your own!" As if their "consent" to collect the data in the first place were any less flimsy than Facebook's.
