I'm with you, but incident has different meanings to different people. For example, in high school, the administrators used incident to refer to fights. The aircraft came to rest with the tail broken off, which is certainly more than $25k in damage as defined by NTSB 830. Since it didn't "crash", they have to call it something and "hydraulic system failure of unknown origin that resulted in possibly departing the runway" is just too wordy for headlines, but it beats the "technical fault" used in many places.
