There is a difference between not supporting mods in a technical sense and not supporting them in a moral sense. I believe here when they say they don't support mods, it's purely in the technical sense. Meaning simply that they have more important things to focus on, like developing the core game, so if it breaks, it's on you. It does not mean that they hate mods.

When you mod there is always a chance that things will break. If you can't tolerate that kind of risk then don't mod--said as someone who actively uses and enjoys mods. But I'd rather have the devs spend their time developing the game than catering to third party modders. Mod support can come later, if they decide to do it.
