I am a full time linux user, but I can guarantee you that if the bigcorps are going through with this it absolutely is going to lock out linux users, because the goal is to stop bots.
Evil.
We shouldn't fight bots. We should use trust instead. Not global trust, it must be subjective. I trust A, B, C. B trusts D, E. E trusts F. It should be weighted. There's small world effect [2]. There's just a few hops between any two people in the world. It solves SPAM, it solves reviews, scam, news and maybe politics. Somebody please get it done already.

Since I wrote it I became confident that algorithm which is used for cumulative trust computation should be up to each node (instead of using zk-SNARks for example). If you trust somebody, you trust them to compute it as they wish. And I would drop dimensionality at least in the beginning. Probably using multiple identities in place of it.
