Unfortunate. Tindie is (was?) a pretty unique marketplace. Amusingly, a lot of what they were selling was probably illegal due to FCC rules: for the most part, you can't sell electronics without EMI certification and "I'm just a hobbyist" is not an excuse. Kits get a bit of leeway, but finished products don't.

Before the tariffs, I noticed that Chinese companies were trying to undercut them. I've gotten multiple mails asking me to start selling my designs with China-based outlets: they would make the PCBs, assemble them, and pay me some money for every item sold.
