Corporations and governments (via specially selected corporations) incorporate spyware into software and electronic devices.
With regards to smartphones users have been deliberately left with a duopoly of spyware manufacturing corporations to chose from, that being Apple or Google.
With regards to Google phones certain brands can be 'de-googled', where one still has to contend with state level players where the spying is done at the communications protocols level.
With Apple phones one cannot 'de-Apple' the operating system, where if one was truly concerned about privacy one would bin the phone.
The word intel in the government community is with reference to the word intelligence meaning data gathering.
The US based corporation Intel, a semiconductor manufacturer hard coded spyware into their processors so governments could obtain the user's data without any boundaries.
This 'malicious' software was undetected for many years.
Microsoft another US based multinational, encoded a 'keylogger' into their Windows 10 operating system.
Microsoft was also 'forcing' people to upgrade from Windows 7 and Windows 8/8.1, because it was allegedly better, better for who?
Windows 10 code base is built on Win7 & 8/8.1, nothing 'new' there, well apart from the 'spyware'.
It is imperative (for governments and corporations) that users update their versions of Windows as each new version contains more telemetry, most of which cannot be disabled at the user level, irrespective of the toggle status.
Thankfully there are people that create programs that can disable the spyware baked into the operating system.
Here is just one example of software, exposing the spyware Windows 10 contains:
During the installation process of Windows 10, all the toggle switches regarding so called 'privacy' were turned off, where this program (O&O ShutUp10) detected another 37 parameters, where a keylogger was active.
If you must use Windows then it should be used in conjunction with telemetry thwarting software.
Microsoft is deliberately screwing its users over in many ways, where this has not been brought to the attention of the courts.
