and for those that think they are actually doing this to protect the children and you are concerned about what your children sees online this might sound a bit harsh but why dont you actually parent. Stop giving your kids unlimited access you tablets/computers etc. back in my day there was the option of having a single computer for the child in a public room that could not be moved. you could create whitelist only sites nowadays very easily even for laymens.
i understand it is a bit harder nowdays because more parents are both working to support the family but i rather not loose what little privacy we have left as a society because its requires more work for you to parent
