People and systems are deciding what you see and do not see every day. From moderators on HN to the algorithms on every Facebook and Google product. When you search on Google and get a trillion results, you are letting Google choose for you by ranking pages. I am extremely thankful for those services as I would be sad if I had to wade through a trillion results and decide what to see/not see myself. I expect these companies and people to filter out BS I do not want.

None of that prevents me from hosting my own website, or going to a public space, and saying whatever I want.
