It showed that users mattered in Bitcoin during the proposed 2X hard fork by signers of NYA which had the biggest mechants and, I believe, by the people who controlled more than 50% of the hashing power. Bitcoin Cash does not have that philosophy.
the biggest thing that the 2x shenanigans proved was that everyone who is involved in bitcoin (users, nodes, miners, businesses,...) care too much about bitcoin and they don't want to destroy it by splitting it into two because of some nonsense argument, and ruin it forever.
in comparison you can see nobody cares about BCash so they easily split it into two and ruin it even more that it already is.
