Mods weren't ever supposed to anybody but janitors. That isn't in a derogatory tone. The anonymous userbase was the original value proposition of reddit. The expertise came from random nobodies. Usernames didn't matter on reddit because nobody looked at it. It seems this is long forgotten history from a time when the internet was primarily IT nerds.
By the time mods were becoming somebodies, reddit was past its prime. Once the power structures started forming it was over. As we're seeing now reddit is hinges on single point of failure. The expertise among the userbase has gradually left the platform long before this API stuff. A long slow process years in the making.
Internet janitors are a dirty but necessary job not unlike the real world. Somebody has to scrub toilets and pick produce. People are a-holes on the internet who need to be put in their place. Reddit has long since become too hoity-toity for that. Now mods are supposed to be experts in their field. Too high to be digital toilet scrubbers. Too scared of "muh free speech" to janitor the Greater Fuckwads anymore. So reddit is an asylum run by the inmates. Expertise can't be assed to contribute to a dumpster.
On another note. The imgur purge has also contributed to the barren wasteland of reddit content history. So many dead posts.
