alt Hacker News> E.g., if you opened an account at a major bank, and your transactions started failing, would you keep banking there?
A lot of people who land in that situation do continue banking there since they are either tied into that bank through loans/debt, or lack the time/energy to move elsewhere.
This situation would lead to immediate and extremely severe legal and commercial consequences for the bank, even if it's JP Morgan.
The argument that a market leader can screw up because it "owns" the market is not correct. Where's Xerox / IBM / Intel now?
