To be frank, this isn't something I particularly fear. You're referencing TV regulation, but the main limiters on TV content are corporations owning the airwaves and people's fear of sex. The internet is not limited in space the way frequency bands are, and good luck trying to enforce pornography laws. Pornography laws are a limitation I worry about a bit, but so far I don't see any evidence that anyone is pushing for using utility regulation to limit pornography, and we can cross that bridge when (if?) we come to it.
