I said to a friend the other day that the problem with all the anti technology frumies is that although they mean well, they are always 5 years behind the times.
The only filter which cannot be disabled is one which is on the ISP level (although if you are desperate then you could probably get around that one too with a vpn, but that wold be far too difficlt for most people).
However, their protection will only remove the absolute shmutz, but it is absolutely impossible to kasher the internet i.e. outside world.
It is oh so easy easy to boot a computer via a usb stick and it is easy to plug a celular dongle (costing no more that a few pounds) into a computer.
The terrifying danger of all this focus on filters is that our community are drawn into a false sense of security thinking they are safe, when in fact, it only takes somebody with a little knowledge mere minutes to bypass most filters (and we know how quickly information is now available online).
The askonim driving the present mania are still stuck at the turn of this century. They still think the internet can be tamed!!
The sooner all communities join together to make an open community run ISP offering differening levels of filtering, the better.
However, in todays climate of I am even frummer than you and blue shirt wearers are shkotzim, we all know how (un)likely that is to happen.
