I think you’re correct in both aspects for sure. Parents are certainly less involved, for the most part, in informing their kids of literally anything. It is much easier to ‘offload any and all responsibilities’ as you put it. iPad kids are a good example of this. Handing a 2yr old a video device and walking away is not parenting. This is an issue with many many topics from internet safety, to general life things, to talks about their bodies. Parents do not want to parent.

I’d also agree, largely, the parents just don’t know, or care. Privacy is, unfortunately, a niche thing to know and care about.
