Do you realize just how much advertising funds? It's a 12 figure global industry and 99% of the content you consume is funded in part by it - and that's before we get to how advertising drives the economy by efficiently matching businesses to customers. Every company relies on advertising (whether paid, word-of-mouth, etc) to succeed.
It's irrational to see so much hate and it's likely your complaint is really only about intrusive ad formats and data privacy. That is something I agree with and I'm for every change that makes for safer, better, and more private ads, but that is vastly different than calling for the elimination of advertising in any sensible reality.
We say the same things with government waste over military and healthcare. And we can fix it in the same ways with better trust, accountability and regulation.
