I don’t agree. They can reasonably argue that advertising is a requirement of their business model, so it is necessary to advertise. Therefore it is necessary for them to block access to those blocking advertising. The directive cited isn’t intended to make advertiser supported services effectively illegal in the EU. That would be a massive own goal. It’s intended to make deceptive and unnecessary data collection illegal. Nothing YouTube is doing is deceptive. They’re being very clear about their intention to advertise to non-subscribers.
