The gist of the article was that a CPAP machine was basically a ventilator with some features disabled in software. Given that there are many of these around, with a 3G internet connection and OTA updates, and that the manufacturer could easily turn a CPAP machine into a ventilator by "flicking a switch", yeah, I consider that an indication that they're "sitting on it". They'd rather sell you a new machine at over-inflated prices than enable existing machines to be repurposed.
