Look, if steel cases were as good as brass, everyone, including the military, would use them. Brass is superior to steel for cases for a number of reasons, such as creating a better seal when firing, feeding and extracting easier, less corrosion of the cases, easier on the extractors and ejectors, better at buffering the impact of the bolt on closing, etc. All of this is basic material science.
commie ammo is for commie guns!
I'd venture to guess that most AR owners dont even know how to clean their gun properly, and like you said, a lot are just lazy.
I'm in a week long SWAT school right now. I shot about 500 out of my AR today, and about the same yesterday. I wipe down and go, no big deal. I'll be shooting another 500 in the morning. It will get the full scrub down this weekend. Would I allow this to happen if I were shooting junk ammo? No way. I'd have to scrub each night. I'd rather be training or resting.
"Just blame Sixto"
First, I don't consider the steel cased Silver Bear and Golden Bear ammo junk by any stretch of the imagination. I've shot a fair amount of the Silver Bear and find it to be at least as clean burning as WWB ammo. My prejudice against steel case ammo comes from watching multiple jams and failures with Wolf steel cased ammo (most likely with the lacquer coating) a few years back during a match on a hot day in July. The Silver Bear and Golden Bear ammo don't share that same problem. Yes, I know the new coatings on the Wolf and Brown Bear ammo are polymer but I'm not willing to take the chance. I've never had any failure to fires, failure to feeds or broken extractors using Silver Bear.
Second, the reason I bought the Golden Bear for shelf ammo was primarily cost. At the time I purchased that 1000 rounds from ATG, I paid $248.95/1000. It is in stock today for $278.95/1000. That's for a cartridge shooting a 62 gr. HP bullet. Compare that to say Federal American Eagle 62 gr. FMJ (not HP) from ATG at $517.95/1000 and I think it's easy to see why I chose what I did for ammo that may never get used.
Third, I currently have time to pick up empty brass and reload for my rifles. Shooting steel case ammo when I could be reloading seems a waste. However, if a real SHTF scenario did come about, I doubt picking up my fired empties would be a high priority so seems like a good time to shoot something you don't have to worry about and that didn't cost an arm & a leg.
So for now, I'll continue to shoot my brass cased ammo while I have the time to pick up empties and reload and save the steel case ammo for when I don't have the time.

I don't think it did any damage to my rifle, but I won't buy the stuff again.
I've had no problems firing any sort of steel cased ammo through any other weapon.
