Do you think you'd get away with photocopying and scanning a paper book?
It probably doesn't violate laws against circumventing DRM, but using it is still potentially copyright infringement.
What it does do that might be useful is legitimately strip DRM from files that aren't protected by copyright or for purposes which are allowed by copyright, where you might otherwise be in trouble for breaking DRM.
Sending a copy to a web server is possibly not covered under personal use, but that depends on the country I guess. But of course he could simply run the OCR locally on his computer instead.
