I disagree that it's as simple as just blaming the parents. As a technical community it is easy for us to assert that there are probably optional restrictions somewhere but many parents who are not technically-minded will not necessarily make that connection. Manufacturers/vendors of these devices simply don't do a good job of advertising to parents about these risks and the options available to restrict them. iOS, as an example, does have the ability to disable in-app purchases using the "Content & Privacy Restrictions" settings, but unless you dig through the device settings and found them (under "Screen Time" no less) then you would not know that those options exist. Given the obscure naming reducing the chance of them ever being found, they had might as well not exist. Apple could do things to improve this. They could clearly ask about parental controls up-front during the device initial setup, they could clearly place them at the top-level of the Settings app and label them "Parental Controls", they could even include a bit of paper in the box or some printed text on the packaging that explains where to find those options. They do none of those things.
