Here are my views on this:

- Windows: The Windows attitude towards privacy isn't good with their telemetry and other data collection increasing gradually from 8 to 10 to 11. In fact, most geeks across the support forums think that 7 is probably the safest and most privacy friendly Windows version but MS is doing everything it can to ensure that newer software doesn't support 7 and it just goes into obsolescence.

The "default" state in which a W10/11 laptop comes today is so privacy unfriendly that it sends all kinds of data like contacts, location, etc. to Microsoft and their "trusted partners". You can't turn off this data unless you've visited power user forums and know exactly where to find those settings, and basic telemetry still won't be disabled of course.

As ironic and unintuitive as it sounds, Microsoft Windows was probably much better in privacy department during the bad old days of Gates and Ballmer compared to the good "open source and geek friendly" days of Satya Nadella!

- Mac: Apple systems should ideally be privacy friendly considering the amount of premium they charge to their products and services. But how well does that work in practice? I've never used an Apple product but those who use them seem to have the impression that they're no good in this department compared to others! Logic tells me that a more capitalist devil should be no different than the less capitalist one, they're probably all the same when it comes to throwing user's privacy in the bin!

- Linux: Linux used to be the holy grail of users who cared about privacy many years ago but does that still hold good today? Ubuntu was also in some data collection controversy or other many times in past, but how are the state of things today? And what about the derivative distros, are they good too?
