The word you are looking for is analogous, not equivalent.

[car_analogy]

No, equivalent. It may relate to a different, more intangible object (website vs. car), but it strips away the same rights.

[darkerside]

In what sense is it equivalent? Legal? Ethical? Moral?

[car_analogy]

Equivalent in the rights it takes away. 'Rights' in a moral, not legal sense - they may not be codified in any law. In the same way one's right to free speech is said to be curtailed, regardless of if their specific legal system recognizes such a right.
