> You own your machine but not the text.
You don't get to own the text just because you can read it, see if you read this - it is still my text (because I wrote it!).
>what would be your opinion if the major websites would put a T&C that you have to enable (Let's say it was safe JS) ads to view content.
And how would I know it's safe?
I don't even let the closest friends on the wifi because they don't run adblockers on their phone and I don't want my router to get pwned [1] just because someone like Forbes is making a buck using Ads.
> Would you still say "it's my machine and I view what I want when I want"?
It is still my machine, so long as I physically own it. If I run a virtual machine in the cloud it's not mine you see, because then I'm just renting it. If ad networks want to remove the ability to block ads they would have to own the machines and rent out those computers to users, they are free to do this.
