I worked in finance for a bit. The knowledge moat for tech is far greater than that of finance. I wouldn't be surprised if a tech company breaks into finance and traditional finance companies can't compete with the tech moat.
The SOP seems to be to find some dinky bank with an established license and acquire it to get a seat at the big-boy table. I suppose, then, it inevitably leads to a culture clash as the "Bank people" can say to the "Tech people" that the moment they stop playing ball, the whole thing crashes down.
