I know. The examples were still factually incorrect straw-men.
> it must be legal and ethical to block them
That's the point; it is legal and ethical to use data that was voluntarily given. If you want control over how things are used, stop sending to everybody freely and require a contract.
> harass those who spend money on them.
Clicking a link isn't harassment.
You are making people lose money (not the malware adnetworks, not the trackers, but the guy buying advertisement) to prove a point to the ad-network (which is actually making money off this), I consider it close to harassment.
So now when you run this program, the two entities you're most against (Google for not having safe-ads) and the content website (for not working for free) are actually getting payed!
If you want to hurt Google, just block ads.
Yes, that is one of the intended goals.
> not the trackers, but the guy buying advertisement
Targeting the source of funding is often an effective strategy.
> {,malware} ad-network
> trackers
> guy buying advertisement
All of these are responsible, so they are all intended targets.
> I consider it close to harassment
If following a website's href suggestion to load a URL is "harassment", then advertising is also harassment.
