I got a response from RogerRabbit, a real mycologist on the forum. You can consider him the foremost leader in mycology, he's been growing for decades and almost anybody that is growing mushrooms in the world can thank him because his research has influenced every technique that exists for growing mushrooms. Here is his post copied and pasted from the Shroomery:
"Absolutely bullshit, period.
The CO2 content inside a spawn bag can reach 20,000 ppm, but that's INside a bag of less than 1 cubic foot. I currently have over 500 of those spawn bags in my grow area and the CO2 level of the air is barely above ambient. Don't buy into this internet scam. It's not based on mycology, but on ripping off those who don't know any better.
