Unless you live in a third-world country, you're not going to have all the options you have now, in the future.

And if you go around using the web unaware of how they're doing all this, Farcebook, for one, are tracking and data-mining you even if you've never visited their website.  This illusion you both have of thinking that "if you don't give them anything, they don't have anything" - is an absolute load of crap!  You don't have to give them anything, these corporate monsters are taking it from you without you knowing it, and without you giving them permission.

As for you punching the nag screen, you should not have to deal with that nag screen in the first place, isn't telling them once good enough for them?  You paid for your software and you should be left in peace to enjoy it, but instead, what they're forcing on you (even without the upgrade) - is automated harassment through a persistent nag screen that will not take no for an answer.

• Using Debian, I don't even need to know the meaning of a "Nag Screen" - because they don't exist.
• Using Debain, my user-data will never be compromised - because the OS doesn't gather it in the first place.

Figure it out.

Live in your fantasy worlds by all means, but if it were possible, I'd bet my life that using Debian is the safer option than any commercial OS, because it's impossible for me to loose that bet.  You can either know when your argument is defeated, and accept it like a mature adult, or you can go on kidding yourselves.  I realise you didn't address me in your post, but from now on I'm asking for no-one to address me in this conversation.  I'm sick of trying to explain things where the logic is so obvious that even a child would grasp it without any difficulty at all.

Trust a commercial OS and you'll pay the price further down the line.
Over and out.
