Seriously, why does this bother you? I admit it doesn't really add to a discussion, but if I had a dime for every time I heard that TouchWiz is garbage without an explanation, I'll be making serious $$$. As someone who likes TW, I'm not going to cry foul every time someone says it sucks.
You said it yourself--adds absolutely nothing to the conversation and more times than not leads to a pages long bickering match, often with a closed thread. It can suck having to sift through posts to find one actually pertinent to a discussion.
I don't take any personal offense to any of this nonsense, always found it amusing how people jump to defend a particular phone, platform, etc like a mama bear defending their cub or someone who's sole existence on these boards apparently is to incite the very bickering conflict I previously mentioned. I'm not paid by any of these companies, don't have significant investment in any of them either so why would I care if anyone here likes/dislikes/loves/hate any of the devices. I'll admit I'm no saint on here either with an occasion shot taken, but usually it's to dispel something that I don't necessarily find to be true. I try to be objective, don't alway succeed.
What I do like is being able to come and have a reasonably civil discussion that actually has some useful content, maybe debate the merits of a particular device, or even ask opinions or seek advice, and posts like the ones I highlighted serve absolutely zero useful purpose.
So yeah, I called 'em out on it.
