Dude, that's a really bad misrepresentation and very unhelpful to all the people who do need one. Many of them already struggle with self-worth issues, and seeing (whether intentional or not) lies like that spread, or worse, parroted back at them by others later does not help that.
It's made a lot worse by the alternative being to gamble on suffocating in your sleep, or doing brain damage to yourself with prolonged apnea periods that drop your blood oxygen, or at the very least, having a shit life due to low energy levels every day from having been 8 hours with the blood oxygen level of a 90 year old.
You're still breathing entirely under your own power with CPAP devices. All they do is basically balloon you up a little to keep your throat from closing up in your sleep, by providing a continuous flow of air pressure higher than the ambient air pressure. Yes they have an up/down rhythm that matches your breathing, but that's not because it breathes for you, but because it literally matches your breathing patterns so it won't obstruct your own breathing.

Also, to be honest, this is ridiculous. Medicines to help your body regulate gastric acid exist and aren't particularly expensive.
