Counter example: I supported and still support a little a few great creators. So "no one" is already wrong. It does happen. It might not amount to a high monthly salary. Most likely not. That's a point you can reasonably make, but you can only wrongly claim, that no one donates.

(I deem periodic support as donations.)

>Conversion rates across the board are around 1%. And then of those donations, most are the lowest tier/lowest increment.

Then what is this: https://graphtreon.com/top-patreon-creators/video

Not the most common way to make money from videos, for sure, but it's not "nobody", and they need hosting.

If you are talking about "conversion rates" then yes donations aren't for you. Go somewhere else.
