They do post their financials, so I'm sure there's an explanation. But I don't think they are nearly as established as Framework, despite the company's age.
I think the problem with Fairphone is they are closed off to a very small market. You can't grow, or be a leader in any market, if you're restricting yourself to Europe only.
I would be more than happy to give my money to either Fairphone or Framework before spending more on another Samsung phone that has planned obsolescence built in as a feature. But, I can't unless I import it and be stuck with not being able to actually get parts like the product is intended.
