It blocks some of them, usually the most basic. I also seem to remember that by not answering those prompts (and hiding them instead), you actually consent until you decline.
It absolutely can't block the more advanced, sometimes multi-stage prompts Google, Youtube, and many newspapers use. Consent-o-Matic actually goes through those prompts and declines the maximum possible amount of tracking, while consenting to the necessary options required to make the site work.
That is false, you only consent by your explicit action - clicking "accept". If you inspect element and remove the consent popup entirely, you have not consented.
Exactly. Consent is opt-in, not opt-out. That's the law.
If a website does not respect that, it probably won't respect your choices either, so you might as well block the cookie banner and all tracking scripts.
