To be fair, "fiber" is a pretty well known term in the context of concurrency. The post author did not make it up.

What an awful choice of terminology though - it’s almost designed to be confusing to anyone outside the space.

Maybe, but "thread" is a widely accepted term even though it's closely related to "fiber" both in concurrency (coop/preempt multitask) and general day-to-day sense (textile).
