I looked at it the exact opposite way. To me, the headline was flattering. It shows that Western Union sucks $400MM out of people while providing a service that is easily moved to cryptocurrency. I see it as a declarative win for Bitcoin by showing how it actually saved Salvadorians a lot of money.
Its also common knowledge that Western Union and their ilk have been exploiting and sucking dry people who live on the margins of our financial system. Any article that says they're loosing money to a competitor is fine by me.
Even as someone who hates the crypto hype, I have to say this time the crypto-win is legit.
