Just registered on macrumours to answer this.
A. ~2 yr old iMac. Faced same 56500 charge (~700$). In touch with original poster. Case is ongoing.
B. Lots of ppl who faced the issue are asian. Hence, it isn't widely reported as many of them might not be even aware of such communities.
C. I've been one of the biggest fans out here. They say one bad experience shouldn't ruin everything. But how they handled and managed it definitely ruined it. (More on it later)
D. Here, apple outsource repair to third party. Was given 650, 2450, 2850 - 3 different estimates to repair itself. Apple doesn't care. Third party is apple's way of avoiding deniability.
E. U can't do anything except going to repair stores. He wasn't even ready to send me estimate as an email. Basically u get what they did after u pay up. Very very shady tactics. Apple say they don't have any control over it.
F. Wrong. Apple does have an control. Gsx2.apple.com is where they manage all device.
G. Fact. Senior support staff from India is far worse than chat support staff on US (they understand frustration, read issue or even file feedback or pull up anything asked. He even arranged call back. But again, it was from higher ups in india, and they don't want this issue raised)
H. U will say what's the issue!?? For most of the ppl (including me), screen had horizontal line. It could be bug, something causing part to burn (this was new design) and many ifs.
-- currently, it's not that much known because some apple engineer probably fixed it via software update (think of Tesla updates or whatever idk)..
It will only be an issue if there is an another lawsuit in USA. Or people in EU or other place start scaring apple with lawsuits.
(P.s. haven't reread. This is just all summary and bits coming together in case it helps)
