The most offensive people to me are those that feel the need to do everything they can to impact other people simply because those people take enjoyment in something they don't like personally and has absolutely no impact on themselves as an individual. Seriously this started with the OP complaining about what other people "might" see on their own screen that they can neither deny or confirm unless they actually look at the person's screen or get sent a screenshot outside the game. Texture swap has been around for decades. Is it against ToS? Yes technically, however most game companies generally do not care in this regard because the swap is only visible on the client side. Unless that texture swap results in an unfair advantage in game it has no impact on other players.
