They are a massive monopoly and just the other day it was reported that they manipulated their own ad markets for their own profit. They constantly inaccurately accuse people of malicious intent and copyright infringement, often massively hindering peoples' careers and generally providing zero recourse. To not assume lying and at best self-serving intent given Alphabet/Google's position in the world would be foolish.
On top of that, is it really that different to use inaccurate AI or to use humans who are intentionally not given the time or tools to do human-quality work?
The problem is obviously with the overall quality of moderation, and the level of power exerted by platforms over users. Whether a non-skilled human reviewer or an AI is handling the broken process hardly matters given the results.
The point is that involving more humans in the moderation decisions at YouTube does not guarantee nor is there any evidence to suggest, that it would result in better moderation.
Somebody with the technical and industry knowledge to know that talking about security vulnerabilities like this shouldn't be removed can probably find a better job that YouTube video moderation.
There's a very wide chasm between "an AI decided" or "someone spent 20 seconds on it", and "we hired an expert in every possible field and they thoroughly research the facts at hand before making a decision".
The latter is obviously not feasible, but there are many options in between that will give markedly better outcomes than the status quo while not making YT moderation economically infeasible.
I'll settle for "Google makes a well-informed decision and will communicate the weighted pros and cons that led to that decision."
That's why I turned this around. Why do you assume they're lying, without evidence?
