However it is an ethical dilemma, especially in a World where Contributor exists. Content is not free, hosting is not free, development and the application of security patches is not free. Currently sites are monetised using ads, and by using uBlock you're getting for free something that is not free. You are also inevitably causing people who do not have uBlock to 'pay' more, or contributing to putting the site out of business.
While Contributor obviously doesn't prevent Google from tracking your every step, and I'll still take steps to avoid data harvesting, I'll be buying it the moment it's available on any of the sites I read regularly.
