Sounds pretty wild to call it unethical to buy the game because of WoC (which isn’t even the one responsible for the game). I doubt their worst act even comes close to a normal Tuesday for a lot of companies you likely buy from, directly or indirectly.
You can look up Larian if you want, but they are far from a big game publisher the way EA or Rockstar is. And they are going against the trend of mtx or DRM. Pirate if you want, but using morals as an excuse for not wanting to spend money doesn’t really fly in this instance.
