99 people are Justin Beiber fans
etc...
I don't want to censor (from YT comments) people whose comments I disagree with, or consider stupid or shallow, or even people that are undeniably racist or ignorant or whatever.
When it comes to law, I'm against almost any form of censorship, and wish we had less of it than we do now. So I would be strongly against any law that would force YouTube to censor themselves.
I wouldn't support a law banning doctors from blasting DubStep in their offices. But I wouldn't choose a doctor who did so.
I don't support forcing companies to censor users, but I prefer to visit ones that moderate their comments.
If by "niche tools" you mean "billions of people, of all races, countries, beliefs, politics, religion, ideology, etc" participate in it, and no single ideology or ethics prevails, unlike in 99.999% of internet sites, then I agree.
I have no problem if 10% of videos have all the comments from the "worst" 10% of YouTube users. It just turns me off to have the "worst" 10% spraying bile and stupidity over 90% of videos on Youtube, scaring off the "best" 10% of users from leaving their own comments.
Note: I invented these percentages, and "best/worst" is subjective.
