Just as much as any other corporation or an average human bean. Everyone is for himself here and they will screw you as hard as they can to get what they want.
This does not mean that they can deliver a quality product at the same time, except when screwing by itself involves delivering a mediocre product. That is when instead of adding a new mechanic/quest to get the rewards (as a subscription player at max level) they just throw out those rewards as cash-shop pets/items/mounts. This is a lazy way of making money on side of the developer.
Same with Valve with hats and many others.
Golden age has passed.
