I don't get why so few people are ready to accept the fact that they live in public now. [...] EA knows my video card
Not the main point. Who cares about your video card or how much RAM you have.
The main concerns are that
- you don't know what data they collect and what data they might decide to collect tomorrow
- you don't konw who else can trivially collect the same data or any other data
- you don't know what vulnerabilities are in their malware and who else will use these to access your computer
- if there are vulnerabilities in the malware, there is usually no way you can protect yourself against them
Facebook and Google know far more intimate things about you than EA ever will even if they literally copied your entire hard drive.
Facebook does not know I even exist. If you choose to put your life on there, it's your decision, but then again, it's your own fault. I fail to see the need for Facebook, or Twitter, or what they're called. Who cares what movie I watched last night, whether my date showed up or not, and who wants to know that I just came back from the toilet. And whose business is it anyway...
Google certainly knows the contents of any of my non-work emails for what it's worth (since I use gmail). The most important thing you can learn from my email is what I ordered at Amazon last week. Go ahead, feel free. Regardless, they'd better not get caught using that data or passing it to a third party as long as they have a single subsidiary a EU country. The USA may be the Wild West, but in the EU, such thing is a serious crime, and you do not want to be caught violating telecommunication and privacy laws. Google also certainly knows what I (or possibly someone else on my subnet) have been searching for on the WWW during the last 10 years, but again there is not much harm in that (this is data which they may actually use and hand to a third party too, supposed they don't link it to my personality).
The important thing is,
they don't run subversive software on my computer. They don't see what's on my hard drive, they don't know the password for my bank account, they can't read personal files such as my tax declaration or letters to my grandmother, they can't download my last holiday's photos. They don't know who I work for or how much I gain. They can't turn my computer into a botnet zombie by flipping a switch.
And that's the one big difference. The companies that install privilegued (or even rootkit) espionage software on your computer
can do all that and enable
others to do it, and you have to trust (or hope) that nobody will.
