Not sure how preferring things like rectangles stops you from

Probably has more to do with the other features of Visio. Hidden metadata,
slow VBS, fragile registry dependencies, ... all of which engineers tend to

Not trying to start a Visio religious war, just saying there's a reason
enterprises use it.

Like most things enterprises use it because that's what they know. Managers
also believe they "can't get fired for buying IBM". They will likely continue
believing this until another manager comes along who knows open-source and how to use it for a better ROI.
