From my limited perspective, it seems like the community wants mod support, but they were mad about some combination of these things:
- Updates and hot fixes don't come quickly enough
- Updates sometimes break a large number of existing mods
- Not enough new features or explicit support for certain mod features being promised
- Things they promised not working as well as people hoped
This isn't everything, but it's what I observed for myself. As you can see, there's some contradiction here, and some of that comes from different people in the community, and some of it comes from people who just want to be mad at everything
For whatever it's worth, most people seem to be just enjoying the game and are excited for anything new coming for it.
