So I disagree with the majority of the OP as modders like Lemming, PowerCrystals(Despite not being on FC), OhaiiChun, and many others are a breathe of fresh air compared to modders from many other communities. Most of the time streamers and youtubers are casting from playing on FC/2 they aren't doing it to grow their epeen; they're doing it to give you a look at what you can use in the future. That said there is only one mod dev from FC that I know of that is "elitist" and only one other than has changed a good deal because of his mod. The latter is Pahimar.
I know I'll get a bit of flak for saying that, but to be sure I love Pahimar. He's an amazing modder and I have talked to him many times in EddieRuckus' streams and is extremely fun to talk to. The only problem is since the end of EE2 he took HUGE amounts of flak for it. I wouldn't be surprised if he got death threats of his own. EE2 was large in part the most polarizing mod(Second in topic only to technic/tekkit) of the MC community. He has since, and understandably so, taken on a "fuck all" attitude when it comes to the topic of EE2 and most of the things from it. I do hope in time he changes this because EE2 had tons of wonderful things and refusing to talk about them or accept ideas for even balanced versions of them(I understand this can and is being compensated through open source code) seems like steps down the wrong path.
The only modder I've seen be elitist of the level of FlowerChild is cpw. He seems to classify modders(Only ones that are his friends) as a completely separate class of people which is usually what leads to this kind of stuff. Two of his larger changes lately were the filler nerf and the removal of book enchanting IC2 tools. Many would argue these two changes were seeking of balance but really when I see cpw talk about the changes... it's not at all. He's more "Haha you can't use that anymore because I say so". A prime example of this to me is the filler change. He specifically changed it so that you cannot undue it and made it non-configurable. Again many would say this is balance but for anyone that's ever looked through the configs there was already a config option to make the filler destroy blocks it mined. the only change that needed to happen was to make the default of the config file set that to true. If anyone has any logical reasoning as to not do that please do tell. The change to the tools was basically a nail in the coffin for IC2 tools. The only thing they had over Tinkers tools was speed when they could be enchanted. Now they don't have anything on them and are basically weak, expensive versions of the power tool from MPS. It does sadden me that he seems to be the ego stroking kind of modder because of the huge amount of things he's added to the community but nonetheless the attitude is still toxic.
