So do you think none of those people actually care about combating hate speech, terrorism, child porn, etc? Or do you think they just see these things as usual tools to get power - and to what end exactly?
No, there are definitely people who care about those things and those are things that should definitely be cracked down on. But human nature always prevails and the power hungry always want more power. "Won't you think of the children" is sort of a punchline for any sort of barely-masked power grab legislation that has gone through in the last few decades.
