Ask HN: What are we doing about Facebook, Google, and the closed internet?

There have been many, many posts about how toxic advertising and Facebook are (I've written many myself[1][2][3]) for our internet ecosystem today.

What projects or companies are you working on to combat filter bubbles, walled gardens, emotional manipulation, and the like, and how can the HN community help you in your goals?
