they dont even listen to and see the whole picture of what happened, instead they just want to "REMOVE GT BECAUSE MALICIOUS BWAAH BWAAH BWAAH"
You are correct that someone like me doesn't know the whole picture. I've only used FTB for about a week and have been waiting for an updated version, but I never had an account on this forum until today. I found out about all this mess by random chance, since I check FTB for possible updates or news fairly frequently (usually not the Forums part, though).
The thing is, from my perspective - and I may not be alone in this - I find that a deliberate game crash trumps all else. The whole picture may be interesting, or merely "popcorn material", but I don't care when it comes to forming an opinion on the matter: a game crash is so bad, so extreme, and so wrong that all other factors, reasons, excuses, justifications, and rationales combined will not match it. It's about the biggest no-no that a modder could do, short of doing damage to non-Minecraft files (ie. Windows system files, stuff like that).
I wasn't against the Greg of GregTech, simply because before today I didn't know he existed. I've used the
mod before, including during my brief experimenting with FTB, but (and this is unfair to mod makers), I didn't know anything about who made it. And I'm not against the mod, since to be honest I'd never looked in detail into what it did. So I don't fall under the parasol that you've staked out, under which "they" sit and sip Rum&GregHateCola in their "I Hate GregTech" t-shirts. I'm not "they".
What I am is someone who was checking for information and found some, and it detailed someone deliberately introducing game crashing in order to... wait, I'm not going to even say why, since it doesn't
matter why. The game crash is the end of it all, the end of the discussion, the end of the reasons, the end of all arguments. Nothing can trump that, no words can counter it, no justifications can explain it away.
I will say, though, if the maker of GregTech were to state, flat-out, that he would never again deliberately introduce a crash to the game, I would definitely give him a second chance. As it is, I cannot trust what he makes. Suppose I use a mod that he has decided to make war on, and it causes a game crash, and I (as a very casual Minecraft player who hasn't played for MONTHS and almost never check into the forums here or anywhere else) have absolutely no idea why it's crashing, or what I've done "wrong", or how to correct it.
EDIT: Further, let me state that as someone who has faded from Minecraft because I find it absurdly easy after reaching even iron armour (it becomes practically impossible to die without suicide), I definitely like the general idea or intent behind GregTech. If I'm not part of the target audience, I'm probably fairly close to it.
