Yes, and it took him 2 years as the developer of one of the biggest JS frameworks with thousands of users to reach that level. And even then, over 80% of his Patreon comes from 3 backers at 2000/mo and 18 backers at 500/mo. I assume those are all companies. The revenue he has from individual users is peanuts.

I hope Patreon doesn’t take a percentage out of that..

Why wouldn't they...? Shouldn't they be compensated for the service they provide?

They don’t provide a thousand times as much of a service as they would if the donation was $2.

I'm sure Patreon's credit card processor is just as benevolent as you expect Patreon to be...

Do US people really pay monthly recurring $2000 donations using a credit card if it takes a percentage fee?

I don't know of any other way of paying Patreon...

Patreon take 5%, as I understand it.
