Not sure if it's all that good a reason, but at least when taking wine to a restaurant that is strictly BYOB (i.e., without a license), there is no chance whatsoever that they will already have the bottle you brought on the list (in which case you would typically be asked to buy what they are selling, correct?). Although honestly, that's not much of a reason -- I've never bumped into it, and how often would that actually happen, assuming you aren't bringing in something so common you could expect to find on every wine list. Plus, a simple call to the restaurant would avoid the problem.
Another reason may be that many BYOs have $0 corkage (e.g., last night I ate at one of those). Again, considering that most places charge only a few dollars for corkage, that in itself is not a very special reason to favor a $0 BYO spot. But I know that many people are very uncomfortable with markups on wine, and some restaurants charge "punitive" corkage ($30 plus) meant to discourage the practice for all but the most special bottles (i.e., soemthing that already cost hundreds of bucks, is particularly rare or special personally, etc.)
As another possible reason for seeking out BYO-only restaurants, there may be a general perception that restaurants with a wine list are more "serious" and more likely, just as a matter of course, to also serve excellent food. Accordingly, if you accept that premise, then it would be a great "find" to locate a BYO restaurant (typically an independent "hole in the wall") that is also serving excellent food. That's kinda crazy, too, as it's premised on a false idea (see, e.g., Olive Garden).
But people have all sorts of irrational (or just non-rational, emotional) reasons for favoring certain restaurants or types of restaurants. Maybe there is just something attractive about the atmosphere of the BYO, or a feeling of doing something transgressive (ooh, it's like we're at a speakeasy)? Or maybe folks do it out of fear of ordering from a wine list? There is more informality, you don't have to be able to pronounce the name of the wine, you won't get looked at funny, or feel bad about ordering a "cheap" wine? Those psychological pressures (which can be eliminated through a little education) could push many people to the "friendlier" BYO restaurants.
These reasons are all speculative and getting less and less convincing as I come up with more. Anybody else care to chime in?
