Earlier quoted context omitted.
The internet and web existed for a long time before everything became infested with advertisement: Hobbyist bulletin boards, Wikipedia, the blogosphere, etc. These had enough content that a single person couldn't consume it all in a lifetime.
That internet was also only interesting and valuable to a fraction of the people who use it today. And if you don't care about that and you are thinking from what you might get out of it: an internet where 99% of the content is crap but universal will end up with more valuable content than a neutered internet that can prevent the emergence of crap, but is tailored to appeal only to 1% of the people. IOW, no one cares…
What I'm wondering is why do you feel the need to dismiss people's niche interests like this? You've even been rude about it in other answers, calling it "masturbatory".
Not everything has to be for everyone. Not everything has to be for you.
