I believe Google is just an ad business unexpectely found itself to be a media company figuring what standards to adhere. IMO their try to be unbiased is a bit awkward.

That's no excuse. If they weren't chasing giant growth, then they could have dealt with the issues as they arose, but instead they're largely turning a blind eye. I've seen so many advertisements served by them that were downright trash (as I've said before in other HN threads... I've seen adverts for: outright scams, malware, gambling, mobile games with extremely exploitative monetisation, porn, incest porn games) and they are tirelessly working to take away any privacy I might have to keep showing me this shit. Then they claim that at their scale they can't do anything about it (or downright ignore it) yet they're the ones who chose to become that big, in an effort to chase profits.

They chose profits over people, that makes them evil and makes people who work for them, knowingly making it worse in order to collect a higher paycheck, also evil.

My experience with youtube is different. I've never seen an ad which I considered inappropriate, nothing from what you listed. So commenting on that I was mostly focused on content rather than ads. For ads, I think, it is pretty clear that what you mentioned is inappropriate.

But the subj IMO is just an exception which probably sneaked through in the disguise of social ad or something.
