GTNH has done more for Minecraft than Microsoft has, arguably. The level of care and work there is incredible- and that’s not just because I’ve contributed a bit here and there.

They've made it easy to fix things too. Just yesterday I ran into a bug in one of the mods they manage, I dreaded setting up deobfuscation and all the stuff necessary to get modding for an ancient forge version going, but nah - they've automated and standardized all that. It was just download, fix and build.
