Just like how carriers can add bloat, they can also remove software features on their branded devices. Sometimes they just bury access to them by removing menu access (meaning sometimes there's a workaround with a special app designed to access them again), and sometimes they remove those features completely. In either case, they are not something the carrier is going to give back when paying off the phone. By "unlocking" a phone, they mean you can take it to other carriers, not unlocking hidden features that may not even exist on your version.
For the RAM management issue, just ignore that. Android is designed to keep RAM full, and arbitrarily killing off apps with these gimmicks only results in that free RAM being re-occupied in the background again. You didn't save anything. All you did was cause more battery use by killing and then initializing apps. If you have a run away RAM usage problem, it's best to deal with that app directly, not talking a shotgun approach.
