If you take out your first sentence and your last phrase, which are both subjective, isn't the rest true for all forms of current censorship?
I'm having a hard time reconciling my thoughts that censorship is bad with the fact that I'm thankful that some stuff is censored. Is the only difference between the two that I want to pirate stuff but I don't want to look at child pornography?
Also, I still think that if you're going to call out all forms of censorship as something bad, that the ends never justify the means, than you better be prepared to answer why you're already censoring stuff.
By your logic, we should all live in government-run internment camps, just in case anyone wanted to produce child porn. Solitary confinement and constant State supervision would prevent that.
It would also prevent everything good that has ever come out of a free society. Art. Medicine. Literature. Technology. All gone forever.
Is preventing child abuse so important that it's worth trading in our humanity?
There are things that overwhelmingly tip the right and wrong scale, things that are morally reprehensible and harmful, copyright infringement isn't one of those things.
It threatens internet safe harbors and requires intermediaries to act as law-enforcement.
The potential for error is huge and any false positive can be disastrous to online business.
It sets a precedent for government censorship of the internet.
It is hardly a perfect solution, it will not stop 'piracy'.
The problem in question is highly exaggerated and very much self inflected by the same industry that is lobbying for these measures.
