It feels like every comment on this article didn’t read past the first paragraph. Every comment I see is talking about how they likely barely made any money on the transition once all costs are factored in, but they explicitly stated a critical business rationale behind the move that remains true regardless of how much money it cost them to transition. Since they needed to function even when AWS is down, it made sense for them to transition even if it cost them more. This may increase the cost of running their service (though probably not) but it could made it more reliable, and therefore a better solution, making them more down the line.
