Google will not scan your mails, will not scan your drive. Microsoft will not scan you drive. Apple will not process your pictures. Twitter will not control your speech. NSA will not see if you were at a protest, or went to a medical facility to perform a surgery of any kind.
"But does it matter if NSA sees me at a protest?" asks somebody. We will see. We will see. Maybe in a year. Maybe in two. Maybe never. Let's hope so.
Most of things you can self host. Probably the biggest problem is to selfhost videos, as they are heavy.
"But it is difficult to self host, and dangerous" says somebody. Yes it is. Yes it is.
"But I will not be able to talk with my friends" complains somebody. Let's wait how it all pans out. Maybe corporations and governments will not see and control everything we do. Maybe they will.
They have all the money they want. They can make all the money they want.
They have a machine, they can make all the money. It's not about money.
It's about control, it's about their vision of how they wanna see the world.
