Reference materials is actually a big difference.
Let me ask you this question as a counter: "What is the functional difference between me writing a slashfic of Spider-Man dating Green Goblin and Marvel writing a slashfic of Spider-Man dating Green Goblin."
Officiality is not a functional difference. And officiality is all the difference you have there.
And, remember, if we take your definition of homebrew to its extreme, then everything is homebrew. There is zero official content at all.
First, no, that's wrong. Second, I bolded the important word there. If you are taking anything to an extreme, you've lost the argument. For example. Water is good for you. You need it to live. Drinking it to an extreme will kill you. Extremes fail.
Because, what was the Mind Flayer if not a homebrew monster Gygax threw together for his home game?
Holy Strawman Batman! We aren't talking about core rules. We're talking about specific settings.
I agree. Your Strawman alteration is not a useful definition.I mean, the entire game was made by a small group of people in their spare time, for their own enjoyment. Then they decided to share it. So, if all settings are homebrew because functionally they all work the same, then all content is homebrew, because functionally, someone created first.
And that is not a useful definition.
