If you don't like GT, don't use it. There really isn't a reason to moan and complain about something that doesn't affect you.
I really don't see why it's so hard to understand that many of the people "moaning" and complaining about this
do like Gregtech, as a whole, but dislike the increasingly ridiculous changes being made to it, it's easy to ignore a mod you don't like at all, but when a mod you
do like starts to head in a direction you don't like it's understandable that one would find this to be irksome. For example, I don't care a bit about Steve's Carts, it's included in FTB, but I don't care about it, I've never really bothered with mine carts, vanilla or otherwise, the only time I've ever even bothered riding in one was when I used to play on the Brohoof server. If the mod maker suddenly went crazy and started making all sorts of changes to the mod to require jumping through hoops requiring you to craft iron nuggets, cut the nuggets in half with a laser, craft the half-nuggets into nails, and a bunch of other tedious steps to create simple tracks I wouldn't be phased in the least, as you say I would simply continue as I have and ignore the mod entirely. However if a mod that I do like, let's say Tinkers Construct, if mDiyo suddenly lost it, disabled the vanilla crafting recipes for things that TC has alternatives for, made it so it took ten ingots just to craft simple tools like shovels and picks, and then started messing around with other mods as well, disabling the tools from Thaumcraft so the only way to use thaumium was for the TC versions, disabling power tools from Industrial Craft so you had to use TC tools with battery mods, I wouldn't be able to just ignore it because a mod I thought was a lot of fun is suddenly a lot less fun and is making other mods less fun as well.
