I don't want to rain on the parade, but this is e-celeb stuff. They got trending because they are celebrities making a statement for attention and Youtube allowed them to. They have ways of making sure this stuff doesn't happen.
You might ask why would they allow this if it talks negatively about them? Well, I can't pretend to predict the future, but like all past actions against Youtube, first and foremost, nothing will happen outside more strict guidelines for more control and censorship. No amount of bad publicity is going to stop them as they actually displayed children being taught what dildos are and made it trend and recommend to people. How is a video about trafficking being deleted going to change anything this time?
The truth is, either Youtube makes these things happen to stir drama and push certain creators bad into relevance, or they do it to gain more control, as they certainly don't care any longer about major advertising deals. The ones that display ads will continue to do so because they get clicks, especially the clear scam ads that have been running. They don't care if a niche content subject leaves because they have hundreds of others that will take their place making content that generates far more revenue as they target children to click on scam ads.
Meanwhile, each and every time one of these celebs gets on a soapbox, they do so to gain attention and never resolve anything. They continue to use the platform and then introduce a further monetization of content while the quality only drops, keeping the quality pay gated and furthering themselves. Look at the people he wished to name to help his cause: h3h3, KEEM, Cr1TiKaL, DeFranco, shane, someordinarygamers... it is all to have celebrities engage with celebrities and make content. It isn't being directed towards removing finances towards Youtube, it isn't reaching out to massive target content creators or target audiences that make Youtube a venture worth the upkeep, it is to make them have a spike in views and become more relevant, playing the part of the rebel to seem like people worth supporting.
Is there anything inherently wrong with that? I would say no, but it is a repeating trend that is not going to result in anything negative happening no matter who they might appeal to. Even if all advertising was pulled and several massive content creators left, Google will never sell Youtube, Youtube will never improve, Youtube will simply continue. Never be fooled by e-celebs. They don't care about anything but popularity and revenue, and they will always betray in some way what you thought they were. It is the nature of media and the controlled environment of showing you a selected portion of what they want you to see.
Sorry for a long winded reply. TL;DR: e-celebs bad, Youtube bad, nothing will happen, the ride never ends.
