The title is clickbait. They don't want to torpedo it, they just want to make sure that it won't cost them money. You can agree with that or not, but surprising it is not.

There is something to say for that, because banks have to comply will all kinds of government regulations that cost them money. E.g. they have to check their customers for suspicions of money laundering, they have to have some financial buffer to make sure they can deal with financial market shocks.

If you allow competition that takes part of the market share for payment traffic but doesn't have to deal with those regulations, it's not a fair competition.
