Here is the difference:
In China the government decides that you can or cannot view porn.
In the *Account Holder* who pays the ISP decides if he/she prefers to allow access.
It is a huge difference. The sensationalist click-bait reporting is inaccurate, disingenuous and deceptive.
I am in the UK. I am the account holder for the service I receive from my ISP at home via FTTC (Fibre To The Cabinet) and from my ISP on 4G (different company). In both cases by default, i.e. for new customers, the ISPs' filters block porn, gambling, notorious P2P sites (but *not* P2P protocols!) and so on. I *CHOSE* to disable them and I can browse any site (Ok, any site not explicitly forbidden by the High Court of a democratic, free nation with separation of state and judiciary, whose laws are enacted by a body with a democratic mandate).
Occasionally my young (below 10 years old) nephews and nieces visit and they like to use any available tablet or PC to find music, funnt videos etc. Before they arrive I open my landline ISP's page, log in and enable the filtering. After they leave I disable it.
I'm the adult, I'm the account holder and I have the choice. I choose to allow myself any and all kinds of gambling, porn, file sharing, political extremism etc. When minors visit me I choose to disallow the same things that their parents disallow.
This is not censorship. It is judgement and responsibility. Censorship is when *someone else* decides what adults may or may not see or hear. This is *NOT* the case in the UK. The ISP account holder has full control and responsibility. Nobody cares if you disable or enable filtering, it's just a checkbox you mark or not, according to your whim.
Judgement and responsibility are when *YOU, as an adult* have the choice. Minors do not get to decide these things, parents and responsible adults do.
To conflate censorship with responsible parenting (including acting in loco parentis) is inane, disingenuous, hysterical and stupid. Ultimately it discredits liberals and libertarians and does them no service.
