I can't tell if this is sarcasm or if you're serious. If you're serious, please tell me what product you've butchered so I can avoid it like the plague.

Clear error messages only confuse people who shouldn't be using the product in the first place. More importantly: a clear error message at the cost of a few confused users is far more important than an unclear error message that costs even more users hours or days of trouble.

I would far rather have a message that tells me that the software broke because the desktop manager found a crash loop and point me to the crash loop logs even if some other poor unfortunate soul has no idea what a crash log is or can't figure out how to access or understand the crash log.

A clear error message should not necessarily clearly explain what the issue is - a clear error message should clearly explain how to solve the issue, or at least point the user in the direction of a solution.
