Google already knows
What google hasn't found out, facebook has been told...
Yep.
Google knows what people search for, and they’ve been making that their business model for a long time. Even if you take steps for privacy, they still keep a deep cache of IP addresses (which is why VPN is so alluring now).
That is why Microsoft is so envious of Google.
Apple knows!
An operating system (on a computer or device) is the perfect way to spy. That’s why google got envious of Microsoft and Apple and made their own operating system and their own browser. Microsoft new this before everyone, and even tried to package their own browser into their operating system in the 90s and got sued for it.
These guys now want to work together. After several decades, the rivarly and envy is still fierce, but these guy go about in the same circles and the politics is pulling them together.
NSA and the “friendly” intelligence services have it all already....
“Privacy” is a horse and buggy concept—it is long gone...
If some vendor promises you privacy, they are either rock stupid or lying.
