It's far more complicated than that and looking at the complicated details is useful to understand the bigger picture.
Here are some examples...
1. It's now that far more things are on the Internet than there used to be. Some things that used to be huge are now a smaller percentage in an immensely larger space. In some cases they are bigger now than they used to be.
2. Sex slaves and porn are a thing and a problem. There's both more of it and more awareness of it. In many places there are laws about this that companies who process money have to take in to account.
3. Kids and the Internet. About half the 10 year olds I know (which is more than a few) have phones with no filters on them. Kids running wild. If more things were more easily accessible than the culture around screens and handling that with kids will need to change. Kids are ready for different things at different ages and the way they view things during their formative years impacts the way they view and treat others.
I use these to just illustrate that it's more than money, power, and control by the wealthy. Sometimes (like in the case of #2) it's about the most vulnerable.
