At the very least, many products have unpopular features that are easier than one might expect to disable. And that’s quite often down to a developer who disagrees creating or leaving a covert channel lying around to circumvent the feature. Their boss didn’t tell them to put it in, and they didn’t tell anyone about it so that it was insubordination if they didn’t agree to take it out. Just a little something we accidentally left in for debugging or PoC purposes. Whupsie!
