That's not how ad-blockers work. They prevent ads from downloading. And so sites load faster, and mobile users pay less for throughput.

This is not completely accurate - most ad blockers include both request blocking as well as content blocking. For instance it might not be able to block a sponsored tweet since it is returned with all of the other tweets, but it can hide that div on the page.

Check any block list and you will see both rules.

OK, thanks for the clarification.

Nonetheless, many sites do load dramatically faster with ad blocking. That's especially so with high-latency connections. I often use Tor through nested VPN chains, and total latency can be 1-2 seconds. Some sites are unusable without AdBlock and NoScript.
