Except that parents have no power whatsoever to effectively prevent kids coming into contact with harmful algorithms, sites eliciting dark patterns etc. Parents don't have power over multi billion dollar companies that have their stakes in harvesting the attention of kids. Only governments can blanket ban these things. At this point the responsibility should not be placed on parents but on companies.
A kid can follow a basic “todo list” tutorial and open a port on your home router then get friends to chat on that. In that case, how is the government enforcing a ban? We’re expecting some agency to do constant port scans on all its citizens to look for anything allowing writes?
The responsibility is on parents. We can try to push some aspects onto government but that will not reduce any responsibility of parents.
