#YouTube makes money from videos promoting extremism. Its algorithm radicalises viewers, because it wants people to be angrily clicking on more videos.
YouTube is tearing society apart by encouraging us to hate each other:
The most promising ethical alternative to YouTube is #PeerTube, which is decentralised and in beta testing.
You can support development of PeerTube to a release version at its crowdfunding page:

In the post's context, I'm using the term "radicalise" to mean YouTube encouraging negative things like hatred/racism/violence/threats/paranoia/extremism.
Obviously the word "radical" can also mean neutral or positive things, but that's not what it refers to in the post.
