2/28/21 please have your orders in by then! Project Status (February 2021): Now Shipping! (orders still accepted)
This made me think there was some deadline, and that orders were closing (ie. a group buy, like many other niche mechanical keyboard products). I ordered mine on 02-27-2021.
The author has assured me for over a year that I have not been scammed and my keyboard will arrive eventually. However they refuse to give any sort of information about how many are being shipped per month, or where I am in the queue. The blog posts that seem to arrive every other month only discuss how many orders have been accepted, not how many have been fulfilled.
I don't think it's a scam but it's a very poorly run business. If my keyboard ever arrives, no matter how it is, I will not do business with whatever mysterious individual is running the project.
