This seems reminiscent of the guy complaining that the glass picture didn't automatically populate a color that matches the style.
haters gonna hate, there's always going to be something that someone doesn't like about the way the software handles something, it seems as though these were great improvements over bs2 in my mind (more accurate step mashing, and yeast tolerances) but obviously some people would've rather had it the other way.
as far as BS3 capping a default 10% abv, that seems pretty logical as most brewers don't often brew over 10% and to get there you've got to add a bit of extra effort. Knowing all of the ingredients and steps required to beat that alcohol level is something that takes a certain level of expertise, and that level of expertise i feel often comes along with the level of expertise to know why the program isn't doing what you think it should. ESPECIALLY since it's well documented.
