Now do Google
Google is the hidden behemoth. I agree Facebook is a very large scale problem, especially with regards to its very active content and how this can be used to try and persuade that minority that swings elections: the Guardian have an article on this I can highly recommend: https://www.theguardian.com/technology/2017/may/07/the-great-british-brexit-robbery-hijacked-democracy (Edit: I see someone else beat me to it ^^)
However I would like to see the covers pulled off Google. I suspect that the amount of data they gather is comparable to the NSA. Google has been using identifiers now for more than 10 years, and its hard to find a website that doesn't have Google's tentacles deeply inside it, from fonts to scripts to overt tracking mechanisms etc. Google's email has become the de-facto standard, despite the fact that its creepily intrusive (all keystrokes sent to Google, all mails scanned etc). Even large companies and universities now use gmail as their 'solution'.
And of course their fucking phone has become the world's phone. A snooping listening location aware device that monitors all processes on your phone. WTF?
And then there is their lobbying groups, active in the USA, and the UK and probably everywhere. They have very active PR units, cosying up to media outlets.
And soon Google cars? Fuck off.
I would love to see an exposé of just how much data Google now has about a typical person. How did we come to this? Because people are really unaware of the reality around them.
I strongly suspect that within Google's most inner walls, when they think about existential threats to the company, high up if not highest is 'public awareness of what we do'.
Try and live a working week without google - I challenge you. Most websites wont work well or even at all without it, most captcha guards are run by google, most websites use google maps to show locations, you can't use an android phone, a google search, you can't email anyone who uses gmail etc.
What happenned to my beautiful internet? I can read 1984 now and laugh because its quite mild compared to where we are now.
