> Ads are an attack, aimed at your brain.

Ads are an attack aimed at your computer too. They download malicious code to spy on you and gather intelligence data about everything you like, you visit, you buy,... it is malicious software hacking into your computer. The fact that some of the richest companies in the world are the criminals does not make it less of a crime.

The propaganda part is, of course, also totally true. Lies, manipulation, etc. has been normalized when a few years back will have been considered a crime.
