Hi Norman,
as already mentioned the implemntation of an AI in the OS is not a card blank for MS / Apple / Google or whatever Device you are using. There are still GDPR/Privacy Policies/Data Privacy Acts inforce, sure it all depends on the country you are living in. Being concerned about the privacy because MS inplemented the Copilot, is in my point of view and i don´t mean any offense to you, overreacted. We all use mobile phones, cloud drives, have Free Email Accounts, are chating via any Messenger we like, and the most people in the western hemisphere have a Facebook ( sorry: Meta) Account or using Instagram or X. All those accounts are free, even the the companies behind are profit driven. What do you think they all take the profit out of? Right, data, massive ammounts of data. Sometimes highly anonymized, sometimes just that much as the legal requirements are describing it. Even for Amazon the biggest part of their profit is data and their software solutions... not the goods people are ordering.
What does it mean regarding secure working on device / computer? Changing over to Linux... yes one way and as mentioned by the others: it requires a massive learning curve. Just don´t be to convenient in Linux, if you download softwares from dubious sources even Linux can get corrupted. To work 99.9% secured there´s just one way: Air Gapping. Create a setup of whatever OS you´ll like, permanently disconnect it from any Network connection and do the updating manually via USB Drives. The remaining 0.1% will be caused by the fact that on a lot of devices you can´t take out the Network Adapters without damaging or bricking the device, so there´s a chance an Update may activate such an adapter plus a possible user fail in noticing it.
Up to a certain stage we have to accepte that we are users and the (ab)used ones at the same time when we want to drive on the Data Highway and being an active part of the digital world. And nope, AI will most likely not be stopped by the digital industry, regulated (thankfully) for sure but not stopped. Another aspect we have to accept if we want to be part of the digital comunity.
That´s my personal opinion and as i said: no offense, mate.
