Addonbuilder needs its Steam API Calls to be optional. People working on large mod projects need to call, Addonbuilder from the command line on dedicated build servers for automation in PBOs.
There are no Steam Calls necessary for building these addons that are remotely relevant.

See the above screenshot. What kind of person thought adding Steam DRM to AddonBuilder was a good idea?
Why should I waste my time writing my own PBO Builder or Tools when you guys can just remove the Steam Calls.
