That's not really a bad thing, IMHO. Many people successfully make a living creating niche products.

They just offered free batteries.

Nope. I don't think they even recognized the defect till many years later (probably for legal reasons?).

For users, that were still under warranty - they offered free RTC batteries (which also stopped working later).

Either way, I won't buy anything from them going forward.

I appreciate the response, but my suggestion would be to offer a mail-in service program so that users don't have to fiddle with potentially dangerous soldering (ideally Framework bearing the shipping costs or atleast subsidizing it).
