IMO, it's just being inconsiderate of everyone that has been using the large primer 45Auto brass for decades. So yep, user name fits. Folks using the small primer brass are simply making it harder for those set up for large primer 45Auto to reload. Brass is not cheaper. I haven't found anywhere that sells new, unprimed small primer brass, and those that sell used brass charge the same, whether small or large primer. I will not return your brass to you, when it winds up in my brass bag, I put it in my scrap brass bin and sell it. In my view, small primer 45 Auto brass is probably the brain child of some "anti-gun" engineer who thought it a great way to infuriate gun folks. Very much how I feel about Hodgdon and its Pyrodex rusting agent that burns.
