How to get YouTube without ads for free?

Enduring unskippable double ads before and during every video completely ruins the YouTube viewing experience. However, not everyone can afford a recurring monthly subscription just to remove ads.

Skipping logical ads within the video stream

YouTube serves ads integrated directly into the video stream. AdBlock Network intercepts the ad loader. To keep the perimeter firewall updated, the software performs asynchronous read-only requests to multiple independent endpoints, blocking requests from ad-serving domains at the Address layer without interfering with the original video stream.
