I block ads because "native" ad producers like Taboola, Outbrain, Revcontent, ... you get the point. These advertising companies like to show NSFW content at the end of news articles at some sites. Therefore I block ads for the same reason I block pornographic sites.
This was pretty liberating because before "native" ads I felt a pang of guilt for blocking ads.
If Google wants to stop ad blockers they should hide sites that use these obnoxious "native" ad networks.
