Is it actually open source though? The repository description may be outdated then, but it currently says this:
> This is the latest version of the internal repository from Pebble Technology providing the software to run on Pebble watches. Proprietary source code has been removed from this repository and it will not compile as-is. This is for information only.
This just hasn't been updated since it was forked from the initial OSS release from Google, I've started a discussion on the firmware Discord to update it.
