The problems for Schiit I see are that this is not the first time that they've been called out for shoddy design and manufacturing, and their standard response seems to be part denial and part shoot the messenger. If it was the first time they'd been found doing something like this then maybe I'd give them the benefit of the doubt but even going back many years the infamous Nwavguy - Schiit Asgard saga pretty much set the template for their responses, shoot the messenger and be backed up by fans on the Internet then quietly admit there was indeed a problem and do something about it.
Earthing is not advanced or exotic or expensive engineering, it is pretty much as basic as it gets in electrical terms, despite that it is a safety critical aspect of design and manufacturing and needs to be done properly. If not then it results in equipment that can be highly hazardous in a fault situation. I think I said this on the Jotunheim thread, but equipment may perform well or it may perform badly but it should always be safe to use. As an aside, some Schiit gear I've seen has been a collection of very sharp edges, now some say that we're adults and should have enough common sense for it not to be an issue but I'd also say that common sense says that it's pretty obvious that taking the edge of sharp edges (which again is hardly difficult) makes things safer and nicer to own.
On standards, regulation etc, this is something I probably have strong opinions on. I am not a particular fan of the European approach to manufacturer self certification in areas where safety is important.
