those big machines spitting out snow, know that they are spitting out purified proteins made from dead bacteria.
Snowmaking machines do not generally work by spraying bacterial proteins. Standard snowmaking is made from water and air, and bacterial ice-nucleating proteins are only an optional additive used in some systems.
Full reasoning
This sentence overgeneralizes how snowmaking works.
The National Ski Areas Association says snowmaking produces snow by separating water into small particles and freezing them as they move through cold air. It describes ski-area snow as actual snow made from water, not as a spray of bacterial protein.
A resort snowmaking explainer from Roundtop Mountain Resort likewise says machine-made snow is "exactly the same stuff as natural snow - frozen water" and explains that snow guns mix water and compressed air to make snow.
There are also snowmaking systems that explicitly use no additives at all. Ski Apache's Snowfactory says the machine only needs power and water and makes snow "without any chemical additives."
Even Snomax's own website treats its bacterial-protein product as a separate, optional add-on: it sells injection systems where "A metering pump is used to add Snomax to the snow water." That means Snomax is not what snowmaking machines in general are inherently "spitting out"; it is an optional product that some operators may inject into the water supply.
So the post's blanket claim about "those big machines" is incorrect. Snow guns generally spray water (often with air assistance), and only some operations choose to add a bacterial ice-nucleating product such as Snomax.

Machine made snow is made up of exactly the same stuff as natural snow - frozen water... The "guns" allow our snowmaking crew to mix just the right amount of air and water to produce snow on the slopes.

The machine just needs to be connected to a power source and water... The unit makes large, clean ice chips without any chemical additives.
- Injection systems | Snomax
A metering pump is used to add Snomax to the snow water. A centrifugal pump guarantees the uniform and constant mixing of the Snomax solution.
So these snow machines just blast super cold water with these proteins, and the two hit the air, mix together, and immediately freeze into snow.
That is not how the additive is used. Snomax is mixed into the snowmaking water before it reaches the snow gun, and the droplets freeze while traveling through cold air rather than instantly upon first contact with air.
Full reasoning
This description gets the snowmaking sequence wrong in two ways.
First, Snomax's own equipment page says the product is premixed into the water supply before snow is made: "A metering pump is used to add Snomax to the snow water" and "A centrifugal pump guarantees the uniform and constant mixing of the Snomax solution." So the proteins are not a separate stream that only "hit the air" and then mix with the water there.
Second, industry and resort explanations describe freezing as something that happens during flight through cold air, not instantaneously the moment the spray meets air. The National Ski Areas Association says snow crystals are produced by separating water into small particles and "quickly freezing them as they move through cold air." Roundtop Mountain Resort similarly explains that tall snow guns give the spray "time to freeze as it drifts back to the slopes as snow" and that fan guns are elevated because the droplets need "more time to fall before [they hit] the slope", which gives them "more time to freeze and dry out."
So the post's description of separate ingredients meeting in midair and "immediately" turning to snow is not how the process is described by either Snomax or ski-area snowmaking references.

The sticks are so tall because it allows the water time to freeze as it drifts back to the slopes as snow... That gives it more time to freeze and dry out.
