I tried helping family and friends as well however the reasons why I wanted to switch (privacy issues and getting served start menu ads) where not shared.
Most people don't care how something works or the moderations behind it just that it works and more importanty that it works exaclly the same way each time.
Ignoring an ad or slightly modifying your tolerance for a increasing shit process is more easy that trying a completely new approach.
The way Mac OS overcomes this is with "buy in", its expensive so people are more motivated to actually learn the Mac OS way to do things so their purchasing choices are validated. There are more reason but this is a big one.
Just keep yours expectations reliatic. Just because someone complains about windows does not mean they are ready to switch.
From memory the UK gov is trying to (or has?) pass anti-encription laws targeting the big tech giants GAFAM (google, apple, Facebook, Amazon and Microsoft). I am in Australia so not up to date with this.
Its hard to tell from the icon pack they are using but I think this might be a screenshot from a degoogle phone?
For example I don't see any Facebook or Microsoft specific apps. But I do see a nextcloud app which is an open source self hostable replacement suite for Google's cloud apps.
Basically the law change won't affect them as they are not using any GAFAM apps/software.
I read somewhere about having a theory to deploy a space craft that was in a orbit that would bring it close to mars and earth on semi regular intivals. With the idea being the craft is a giant hard drive. You upload via laser when its close and downoald on the other end.
It does not provide real time comms but instead bulk data transfer capabilities.
I tried googling looking for a ref quickly but could not find it sorry.
People are lazy as fuck. Provided it plays their games they don't give a shit about features updates, patches, bug fixes etc.
They probably have no ideal what version of windows is even installed on their machine.
