I don't think their volume justifies the expansion yet. They are an incredibly small company (around 90 people) that is doing a lot more than build a phone.
I'm writing this from a FP3 and I'm a bit thorn because I want a FP4 but this phone still works perfectly. I might get a new battery in the next months as this on e doesn't last a day outdoors anymore. It's also a seriously sturdy phone, already fell so many times on the floor.
Like someone said elsewhere (you?) the most sustainable phone is the one you already have. But that’s clearly not how business works. There’s something to be said for buying their hardware revisions to support the cause-unless they’re taking donations and you’re so inclined. The FP3 could itself become good marketing if you sell/donate it to someone who otherwise wouldn’t have the opportunity and could contribute in another way, for instance.
