Its even worse than that.

All these (centralized) platforms, which are supposed to be safe and secure and state of the art

... are anything but. They all have back doors written into them. And a backdoor is only as secure as the group of people who created it. Meaning, if it was just the programmer, its just a matter of time till someone else stumbles upon it (pressing backspace a number of times to access an account on linux). Also meaning, if the number is greater than one, then everyone (but you) knows about the back door.

Further, todays code is written on yesterdays... is written on yesterdays...
meaning Winders is still running NT. NT with all of its three letter company actual undocumented APIs it was running.

So, today we have these enterprise software packages that are just layers of back doors.

When i got into the real guts of Win95 i was appalled.
Today, i know it is worse. Because the corporate structure can only go in one direction.
