At a previous job I built an internal translation system forked from pootle because the commercial options were so bad (mostly wrt UX). This was 8 years ago, so I would have to do a survey to learn what the state of things is today. It's possible the existing solutions are "good enough" and the switching / retraining costs aren't worth it for most organizations. Not to be too Thiely, but I wonder what a 10x improvement looks like in this space as well.
