I actually don't think the whole Cambridge Analytica thing was that big of a deal. I knew it was going to happen eventually way back when, just looking at the horrible security of apps. All these apps you use on Facebook have access to way more info than they need to run. Same with Android. Android's gotten a little better with newer version at least though. There are going to be more breaches though. Cambridge Analitica thing just had the misfortune of being implicated in the first publicised breach. They like knew exactly what they were buying though, and that it wasn't exactly kosher. They also likely weren't the only ones to buy it...

As far as the advertising, I actually wish I could volunteer a little info so they stop showing me certain ads. There are some I just really don't wanna see. :P

It's scary, but we might be at a point where the tin foil hat people might occasionally be more right than anyone else. I fear whats more that we passed the turning point and it's going to quickly become far too late.
