I find it so weird how we just accept the fact that ads can be for fake things and not blame YouTube/Google for those things.
On my email! I really think Google should be liable for shit like that.
it's because everyone but you have something to gain in that transaction - google got paid ad money, the advertiser presumably got some value in exposure.
Therefore, you, for whom the "harm" has fallen, want to blame someone like google or the advertiser, which google has a form of EULA/TOS to shed all responsibility/liability.
It's just the way the internet is, and the reason for adblocking as a requirement.
Of course all the "online safety" nonsense does very little for our safety against misleading advertising.
