Earlier quoted context omitted.
It's obviously not good but yes, you were an idiot to say it could be the end of Samsung. They make everything from cutting edge phones to air-conditioning. One product in one business area going wrong like this is not going to be fatal.
There was probably a way to get your point across without calling someone an idiot, and if not, you didn't have a point in the first place.
I wouldn't have initiated such name-calling, but I do think the OP's reaction is over the top and silly, given the context.
