At a glance: Paladin swordsmanship is largely in line with gladiator skills on a mechanics-level. I imagine there are certain stances or tricks or techniques that are only given to you as a result of training. Those sorts of things would likely be highly frowned upon falling into the hands of "regular" people - You're giving everyone the secret Coca-Cola recipe, and Coke's not going to like that.
Sword-and-board, though, is perfectly fine. Basic technique and instruction can go a long way to helping people learn to protect themselves, and no one would frown upon that being done.
Soulstones are a point of contention somewhat. We don't know if they're required, but if I remember my fluff right it's reasoned that the soul stone in the paladin quest taking to you is part of why you're able to pick up techniques so readily. I personally don't believe all Free Paladins or Sultansworn are required to have one, but that's also a persona belief without any strong ties into the game (to my knowledge).
Teaching someone is fine. Teaching someone Sultansworn trade secrets is most likely very, very troublesome.
