TI has the same problems that any other large company does: it's inhomogeneous. It would be nice to imagine a single company as a single, consistent entity, but the fact is, there are many departments and many teams working on a huge number of projects. Some of them will be crummy projects by weak teams, some will be awesome projects by experts. Some will be a mix of one or the other, and you'll have great chips with awful datasheets, or vice versa, or anything else you might imagine. LT and ADI have their foibles as well -- not usually as dramatic (regarding the present case, I can't think of an LT or ADI datasheet that's had poor images or formatting*; likely, they run everything through a trained team of editors), but nonetheless obvious in exactly the same form.
*One might argue Jim Williams' deadbug circuits, or hand drawn doodles, are an example against this, but their utilitarian suitability in the document, and charming style, easily absolve such an accusation.
