I’m not sure which comes out ahead if we count all of these kinds of devices. There are probably a lot of lightbulbs and routers out there running some variant of BSD or Linux, but only the manufacturer knows (I mean, you can often figure it out, but who cares?).

Anyway, it is important to keep in mind that the useful “size” metric of a community led open source project is the number of developer-hours being contributed to it, not the number of users. It is a fun bit of trivia that these devices are everywhere, and maybe good news for open source fans’ career prospects. But that’s all.
