Given this, the only reason this is able to happen is because it flew under the radar for some time and then governments take time to legislate. By the time it actually becomes illegal, there could have been years of exploitation.
How do we solve this? Assuming that governments are slow moving (there can be benefits of this), and assuming that there will always be people with more flexible morals who will happily build these products, how do we create a society where this can't happen?
