Being able to tear through the source code of something to figure out why it's doing what it's doing is valuable even if you never make changes.

I worked for a company a lot of years ago that had BSDi licenses for some of it servers and had paid an extra fee for source access and that -did- actually come in handy to me once or twice.

Later, the same went for the Radiator RADIUS server where you got source access automatically with a license purchase.

White box versus black box debugging is absolutely something that can make a difference, especially when something goes wrong.

Yep. I've definitely noticed this at work with some proprietary ('open-core') software that we use, and it's made me inclined to prefer source-available proprietary products over more restrictive proprietary ones as well. It's not as favorable as actual F/OSS, but it definitely makes a bit difference nonetheless.
