Based off some of the comments I read on the website, they are targeting people who are selling Raid Runs for Real Money?
At this point this is where I would say "Who Cares" if people sell "Raid Runs" for Real Money it doesn't harm other players who do not wish to participiate in such activity and the game is free as it is besides subscription (no one forces you to RMT).... This being said "Blizzard allows people to buy WOW Tokens" Instantly get real money in game currency value and give it away for a raid run.
This is where Laws should be passed in countries just like EU, and the Gambling / Loot Box law that makes "Selling a users Time" a legal aspect including in Online Gaming, for example the EULA says you can't sell In-Game Currency, or Items, however if you choose to sell (YOUR TIME) doing the raid or playing the game with another user it should not be a ban worth offense and should be legal. As the NPC says in WOW (Time Is Money Friend)...
Blizzard is a Million Dollar company it doesn't hurt anyone, and disabling add-on's like this on the other side just makes people quit on the other hand, I've not really played wow since Burning Crusade because in my Eyes Blizzard destroyed the lore, and game-play since it's original creation.
