When sites like these host a large part of our culture, I think it’s reasonable to think about non compliance because the alternative is essentially to become a digital hermit and not to be able to understand the world one is in.
I never agreed to have all public spaces for Dr age ad-supported, for example. These illegal monopolies have made it impossible to talk to large chunks of the population without either watching ads or using an ad blocker. That feels wrong.
Just because a place hosts culture, it doesn't mean that you are entitled for it. For example new movies are pay of culture, but that doesn't mean you should sneak in to a theater without buying a ticket because every movie theater requires paying. Compensating creators for their work is a part of experiencing creative works that are culturally relevant.
The US constitution absolutely does recognize that the public is entitled to all cultural works, which is why copyright is required to be time limited.
