> Why not provide each individual users with powerful tools that let them specify the type of content they want to see and when
Tools like adblock/ublock/etc dramatically improve user experience and performance on the internet, yet less than 30% of desktop users employ adblocking. Requiring end-users to set up filters to not be accosted by content that most people find objectionable will generally not be a winning proposition.
I don't think that is a good analogy. In this case these filters would be presented to you as you setup your account. In addition with filter sharing any user would only be one button press away from adopting someones else's filter. There could be a wide diversity of filters and users can change their filter by the minute. Imagine if browsers treated adblock/ublock/etc as integral parts of your experience and not as an extra add-on.
