You are conflating illegal child pornography with legal hardcore pornography in that sentence. Was that just poor phrasing? Why is making legal hardcore pornography opt-in a big deal? So many reasons. First, because there's nothing wrong with it and it's something a good many of ordinary people enjoy. Second, despite the previous, in many societies it's still not considered a socially acceptable think to admit to liking even though almost everyone does, so people are far less likely to speak up in a manner that identifies them in order to protest it. Third, some of the actually banned (and not just filtered) content is rape fantasy, which is a hugely popular fantasy among women, and many object to its being banned. Fourth, and perhaps most importantly, making it opt-in is a big deal because it takes a freedom and weakens it. If we have to ask the government for permission to do something, it's not a freedom, it's something being allowed by government for now, and they can change it whenever they want. This is the same reason people advocate open source tools and non-proprietary protocols—so we have our own freedom of choice and can avoid being locked into the whims of whoever holds the power. Porn is an easy place for them to start, because large subsets of society won't speak out in defense of porn, but I guarantee if this sort of filter remains in place long-term, it will be used to block more than porn. That may not even be their intent right now, but when you have a massive internet filtration system in place, it makes it extremely easy to justify adding in a few more filters blocking sites troublesome to the government in a few years.
