The ocr engine is the important thing. The gocr engine, at least, has

I haven't tested any of those, but at least as it sounded from the
description of GOcr, it didn't support columns nor fonts. I don't know
how this affects for example the recognition of text documents and a11y
and so on, but it doesn't sound ... ahem good. Please correct me if i'm
wrong somewhere. and a question, is there any way to control OcrAD from
within Gnome other than from a terminal?
If the engine is good, and freely licensed, then adding things like
column support is not that difficult (compared to writing a new/better
engine from scratch). While there may be some debate about the
GPL-compatibility of the Apache license, it looks to be 'Debian-free' to
me. There is some non-free code that needs to be removed, as Luke
noted, but it seems not to be used at all in the existing tarball, it's
just leftover vestigial code.
