17.99€/month for my family, so that comes to about 3.6€ per person.
It's a cost that in my opinion is definetly worth it. Yes, it is not 'free', but at least the option is there, it saves our mind and it helps the actual creators of the videos more than watching ads would.
Suppose their was an option to pay for your family to have an ad free experience for the whole internet. What price would you be willing to accept for that?
IMHO, the current ad based model for online content is a lose/lose race to the idiocracy bottom for all.
