How did they do that, put a rootkit on his machine forcing all hits to them?

Well they didn't exactly say "do we have your permission to run your CPU up to 100%, hog all of your memory, and install trackers on your computer? And occasionally, can we install malware on your machine?"

Reminds me of the arguments about not letting in any refugees as some of them may commit a crime.

Once advertisements become sentient creatures and can be considered human, then they should be granted human rights. As it stands though, what you're doing is saying that refugees (who, I remind you, are humans) are basically worth as much as a banner ad on a website. It shouldn't need to be said, but I'll say it anyway: blocking ads is not comparable to genocide. In any way. At all.

Fucking disgusting.

The singularity is approaching! What a time to be alive :)

Except that we do not have a humanitarian obligation towards javascriptlets.

and that is definitely the aspect that reminded me

Can you say for certain that none of the sites you visit run a javascript bitcoin miner?

No, just JavaScript that I never asked for and don't want to run.

I'm not sure what you mean by this?
