You did read my previous post? SWIFT actually agrees with the author that blockchain in its current state is NOT suitable for payment systems (which is no surprise given the current 14 tx/sec limit for bitcoin for example). Maybe some day someone will invent a new algo and it will work. But who knows if that's even possible. Until that day bitcoins is worthless as a payment system.
Author of the original article was almost certainly clueless about Swift's project and probably moreso about the hacks they suffered.
As for FT piece - There's a difference between 'not ready yet' and 'inherently useless or inferior to current systems'. There's a difference between 'not suitable for payment systems' and 'not yet ready to support all 11,000 banks'.
According to Swift, test went 'extremely well' and are 'convinced that these obstacles will be overcome'. Change the title and you have pretty bullish piece.
