Companies care, as long as they wouldn't put themselves out of business caring . Can you imagine what would happen if OCZ said "yeah.. we'll send you a new drive" to someone that smoked their drive? Every time someone smoked their drive they'd expect the same treatment.

If a company started honoring warranties on parts that weren't manufacturer's defects where would you draw the new line? It likely wasn't manufacturer's failure since it was used for a year+.
