Ah, I'm sorry, I of course meant filtering of information from the public, not any personal filtering in a wider sense. I may have been wrong to expect that this was clear.

Feel free to wear sunglasses, welding helmets, use ad blockers ("content filter"), attach ND filters to your camera lenses, water filters to your water filtration systems, HEPA filters to air filtration systems, etc.

If we restrict filtering to DNS, so that it's easy to take the "sun glasses" off, then I kind of like it :)
