Probably the same reason microcontrollers have OTP fuses—to prevent accidental corruption in the field or from buggy programming.

I believe it's because it originally was SD/MMC which was supposed to be a future media for audio and the like for retail sale. I had some read only palm pilot cards like this - books etc were also sold this way for a short period.
