I don't know about vanilla, but so what if the "With GregTech" modpack moves on with its own setup ? Those that are butthurt about the changes can host their own server, write their own reverse-nerfs mod, play creative, and so many other options.
But nooo, you have to force your view on other people.
Minecraft was meant for open play. It still is.
Don't like a config ? Change it.
No config for a change ? Deal with it.
That's life. Learn to live with it.
Did you really think about this argument before you used it?
1.)Having to reverse engineer a mod, enter creative, or whatever else to undo a mod which is far over reaching its boundaries is the antithesis of bringing together the better mods created for Minecraft, removing the tedium from installing them all, and making them all play nicely together.
If I have to write mod A to undo pieces of mod B interfering with mods C-Z (and now vanilla) -and- this mod author is leaving many of these changes out of the configuration changes, this entails that the author of mod B is...oh dear god...
forcing his views onto other people. This brings me to point 2:
2.) That argument is self defeating. Most of those complaining here like aspects of GregTech (and this is at least the dozenth time this has been presented, please pay attention) but he's not making changes, even arbitrary changes, to his own mod. He's making sweeping and superfluous changes because he can, and he's forcing other mods (and by extension, other mod authors) to follow suit.
No, people griping here aren't forcing anyone to do anything. Greg, however, is, and so are you when you argue changing configs and writing counter mods and whatever else to defend something which is blatantly arbitrary and meaningless, and adds nothing by way of content or depth to the game.
By the by, "Deal with it" fits into this point as well.
