Here’s the point I love:
The name ‘Content Blocker’ is something of a misnomer, since this feature isn’t meant to hide or block content, as most people would define it. Instead, they act on ads or scripts which often do block content, such as a popup image which covers what you are trying to read.
Content blockers don’t block content so much as block the stuff that blocks content. They give the user an improved reading experience, improved battery life, and improved data usage.
