Do You Know if You're a Hacker?

We're looking at a couple of dolls that can talk to kids in some way. The other one, we're doing our cloud pets, which are these adorable plush toys. Are they still hackable if the fact you can buy them on amazon, is that still a problem? I just want to get the bigger picture though, because even though we're looking at these two dolls, it's a much bigger issue than that, is it is? It's amuch bigger issue, right?
