People that actually change the world don't need to advertise it on Twitter. I have friends that volunteer in Watts and Compton every other weekend (and have done so for years) that don't need to share it on social media. I can't help but think that this current Twitter slacktivism really diminishes their genuine mission.
Unfortunately, there is no going back here - it's partly the issues, but mostly a totally new culture of a) Twitter wars b) a new generation of people feeling that it's their 'duty' to (act out which I often believe lacks context) c) a press and pop culture climate considerably more clicky-baity and divided (just google cnn headlines from the 2000's, way more tame) d) corporate pressure to 'buy into' movements which is only going to really exacerbate the system.
I've said this before to strong disagreement but marketers jobs are to sell you aspiration - when that aspiration moves off the court and into the streets and politics, and you're gadget/shoes/apparel/cars are being sold with politics, it's not only deeply hypocritical, but it's going to come back and bite us.
I don't really see the underlying fundamentals moving in a positive direction.
People might argue that if 'the system were fairer' we wouldn't see this reaction, my response would be that there will always be something to argue about. The NYT was literally calling for 'Paw Patrol' to be cancelled due to indoctrination of children by 'coppaganda'. While this is an interesting idea, I feel there will always be threads to pull upon for people to be angry.
