I think this is propaganda so other companies can say, "wells Fargo had an issue with this so we are going to start cracking down too". Then they can lay off a bunch of people and not have to give severance.
They fired 12 employees of a workforce numbering over 216,000. Looks like they fired 1000x more employees (literally...12000) last year just because "that's business." What a nothingburger.
