If you go to a thread about abuses by Microgoogfacebook I'm sure you'll find lots of complaints about them and relatively few about the NSA (other than the extent to which they are harming people by co-operating with the NSA).
I use a computer. I have to use Windows to access certain common or industry standard software packages.
I have friends. I have to use Facebook or miss out on events or similar. Alternatively, I have to put more effort into bridging the gap. Facebook also build a shadow profile on me whether I use their services or not.
I search the web with a non-google search engine, I have moved my email to a non-gmail service, my browser is not google, my phone is not Android. Yet Google will still collect data about me for advertising purposes.
The fact that they have no official oversight should be terrifying.
If only that were so.
Facebook gathers data on you whether you give it to them or not. See https://www.dailydot.com/news/facebook-shadow-profiles-priva... for example, but this is generally well-known.
As far as I know Google likewise gathers all sorts of information without asking for it, just from their ads and analytics running on various websites.
Microsoft is a slightly different story.
