Yes this is an area where "the minecraft mod community" in general doesn't seem to understand the (recent) history of the FOSS movement. Not invented here syndrome on a very large scale. debian.net doesn't redirect people thru adfly to download DVD ISOs yet none of the devs are starving, and so forth.
Another area of comedy is the early 90s-like "lets make our own license" and the result of programmers trying to practice law is generally about as comical as lawyers trying to program. Yet the modding community with no sense of history has some amusing home grown licenses (sorry no links at top of my head). I compliment you personally for not falling victim to that trap (I looked at your github) but many modders have some truly weird homemade licenses.
Most of those FOSS developers are paid by (a) consulting/support fees on the FOSS they develop or (b) working for companies which use that FOSS in their products. That works fine for B2B products, but doesn't translate well to Minecraft - nobody really needs consulting/support fees on Minecraft mods, because the hosting services mostly handle that, and they sell hosting at near bottom-dollar.
The problem is that 12-year-olds are not willing to donate, and that is the major audience for most mod makers, unlike Linux distros.
Only a few get to make for the smaller crowds, and they are usually mocked throughout.
Not to mention, companies don't invest millions in Minecraft.
EDIT: MMPL (Minecraft Mod Public License) and Elo's and CovertJaguar's custom licenses are the most prominent examples. Half of the mods don't even HAVE licenses!
