* I'm a dschep, sorry I don't work at keybase
* it's open source
* extensions are easy to unpack & view the source if you don't trust I'm not tampering the extension before upload
* I do no obfuscation of the JS, it's only 201 LOC
Surprised browsers plugin centers (stores?) don't let you just put your github repository and build your extension depending on a given branch (or tags) and then informs the user that the extension was directly pulled from GitHub or other version control sources (and provides a direct link) it would be a little more interesting.
