"Shush" and "Wind Down" are already on Samsung phones, and FB is in good relations with Samsung (see oculus), so doubt this would be Facebook killer. Additionally, Facebook already turn down video in newsfeed (it decreased time-spent), and changed goals to 'meaningful social interactions'. Long term, being useful is more important than grabbing attention (and FB plays long-term game). The fact that FB, Instagram, Youtube, are "grabbing attention", is only byproduct of thinking that time-spent like metrics are good proxies for usefulness (and they were really easy to optimize), which turns out not to be true (or at least they don't tell the full story). Hackernews is grabbing my attentions the most for me, should I blame the ranking model? Most engineers, managers, designers, ... in these companies are people who want to build useful stuff, rather than maximizing short term gains for share holders (additionally none of these companies are paying dividends, so if you maximize value for share holders, you should play mid to long game). If you can make these engineers realized that what they are building is harmful, they will change it. Disclaimer: I worked at Facebook and it from inside, so have different "trust" model for these companies, and expectations how they work internally. I don't believe that there sinister master-plan behind every feature they release, instead, they are complex organisms with many players that are optimizing for different goals (sometimes sometimes seemingly opposite).
